  1. 1.1 Solving Simple Equations

  2. equation - a mathematical sentence with an equal sign ►expressions do not have an equal sign EQUATIONS ARE SOLVED BY ISOLATING THE VARIABLE.

  3. 3) –73 = 21 + q – 21 –21 – 94 = q q = – 94 Solve. 1) g – 3 = 10 +3 +3 g = 13 2) 80 = x – 15 +15 +15 95 = x x = 95 Variable always on the left in final answer.

  4. Solve. ►Find the LCD to add and subtract fractions.

  5. Solve.

  6. Solve. 9) ►To solve equations with a fraction coefficient, multiply both sides by the reciprocal.
