23 and -12
What are like terms
1p + 1p + 2t + 3t+ 1p + t -36 + 32
What is 3p + 6t - 4
2/3 x - 4 = 8
x =18
1 - x + 12 + 2x = 4
13 + x = 4
What is subtract 13 from both sides
DOUBLE JEOPARDY (double points!)

What is 1x + 2x2 + 6
1 - x/5= 12
What is x= -55
4(x - 2) + 3x = 20
4x- 8+3x =20
7x - 8 = 20
Add 8 to both sides
