Do Now. Solving two step equations. 3x – 6 = 6 Add 6 to both sides +6 +6 3x = 12 Divide each side by 3 3 3 x = 4. 9z – 12 = 69.
E N D
3x – 6 = 6 Add 6 to both sides +6 +6 3x = 12 Divide each side by 3 3 3 x = 4
On your own • 7y – 11 = 24 -10y + 12 = 52 10y + 2 = -118
On your own 6 + y = -1 -8 – y = -15 -10 – y = -1
In some equations you need to combine like terms in each side of the equation before you do any operations on both sides.
Solve a two step equations by combining like terms 7x – 4x = 21
On your own 1. 3x + 7 = 19 2. 2g – 13 = 3 10 = 7 – m 8y + 3y = 44 6.
