Writing Algebraic Equations Equations are like scales. Both sides of the equation must be equal. We represent this as: ×= 7 × We can represent this as: 2 + × = 5 × Here × = 3.
What is ×? 4 3 5 ×
How would you represent the items on this scale as an equation? 4 = × + 5 × = 9 5+ 4 = × 5 = × + 4 ×
Draw each equation on the scale. Keep the × in red. × + 2 = 8 4 = 1 + × 3 + 2 = × × + 4 = 9 6 + × = 13 3 + × = 8
