Sometimes you will be asked to solve for a specified variable.
Sometimes you will be asked to solve for a specified variable. • Key Concept:
Sometimes you will be asked to solve for a specified variable. • Key Concept: • Solving for a variable DOES NOT always mean getting a number.
Sometimes you will be asked to solve for a specified variable. • Key Concept: • Solving for a variable DOES NOT always mean getting a number. • Treat every letter like a number.
Sometimes you will be asked to solve for a specified variable. • Key Concept: • Solving for a variable DOES NOT always mean getting a number. • Treat every letter like a number. X + Y = Z Solve for X.
Sometimes you will be asked to solve for a specified variable. • Key Concept: • Solving for a variable DOES NOT always mean getting a number. • Treat every letter like a number. X + Y = Z Solve for X. Remember that in order to eliminate something you do the opposite.
Sometimes you will be asked to solve for a specified variable. • Key Concept: • Solving for a variable DOES NOT always mean getting a number. • Treat every letter like a number. X + Y = Z Solve for X. - Y -Y Remember that in order to eliminate something you do the opposite.
Sometimes you will be asked to solve for a specified variable. • Key Concept: • Solving for a variable DOES NOT always mean getting a number. • Treat every letter like a number. X + Y = Z Solve for X. - Y -Y X = Z - Y Remember that in order to eliminate something you do the opposite.
Sometimes you will be asked to solve for a specified variable. • Key Concept: • Solving for a variable DOES NOT always mean getting a number. • Treat every letter like a number. X + Y = Z Solve for X. - Y -Y X = Z - Y Remember that in order to eliminate something you do the opposite. Note: Z and Y are not like terms, so you CANNOT simplify further.
Solve for the specified variable: X + 2Y = Z Solve for Y
Solve for the specified variable: X + 2Y = Z Solve for Y First switch your X and Y.
Solve for the specified variable: X + 2Y = Z Solve for Y 2Y + X = Z First switch your X and Y.
Solve for the specified variable: X + 2Y = Z Solve for Y 2Y + X = Z First switch your X and Y. Eliminate addition first.
Solve for the specified variable: X + 2Y = Z Solve for Y 2Y + X = Z First switch your X and Y. - X -X Eliminate addition first.
Solve for the specified variable: X + 2Y = Z Solve for Y 2Y + X = Z First switch your X and Y. - X -X Eliminate addition first. 2Y = Z - X
Solve for the specified variable: X + 2Y = Z Solve for Y 2Y + X = Z First switch your X and Y. - X -X Eliminate addition first. 2Y = Z – X Eliminate multiplication next.
Solve for the specified variable: X + 2Y = Z Solve for Y 2Y + X = Z First switch your X and Y. - X -X Eliminate addition first. 2Y = Z – X Eliminate multiplication next. Y = Z – X Final answer. 2 2 2
