Equations, Equations, Equations Solve multi-step linear equations with one variable.

Solving Equations by Adding and Subtracting x – 8 = = +8 x = 25

What happens when two signs are beside each other?? x + (-3) = -9 Do Leave, Change, Opposite x - 3 = -9 The changes are in red! Now SOLVE!! + 3 = +3 Do the opposite & Add 3 to both sides! x = -6

Try this one!! y – ( -8) = 15 y + 8 = y = 7

Solving Equations Using Multiplication and Division -5x = x = -5

Try a Division Problem 1 x = 54

Solving Two-Step Equations 5x + 2 = = -2 5x = x = 5

Try this one!! 6x + 9 = = -9 6x = x = 3

Try this one! + 8 = + 8 x = x = 18

Solving Equations with Variables on Both Sides 2x – 8 = x x - x 1x - 8 = = + 8 1x = 25 or x = 25

Try this one! 3(5x + 2) = 2(3x – 6) 15x + 6 = 6x x -6x 9x + 6 = = - 6 9x = x = -2
