QUESTION 31
Step-by-step explanation:
3x+5=2x-1
Subtract 5 from both sides
3x+5-5=2x-1-5
Simplify
3x=2x-6
Subtract 2x from both sides
3x-2x=2x-6-2x
QUESTION 32
1/3(6x+12) = 1/2(4x-8) + 8
1/2(4x-8) = 4x-8/2 +8
1/3(6x+12) = 4x-8/2 +8
2(6x+12) = 12(x-2) + 48
12x+24
12x+24 = 12x+24
12x+24 - 24 = 12x+24 - 24
12x=12x
0=0
