Question

1-79. Solve for the variable in each equation below.  Show your steps and check your answer.   4p + 8p + 12 = −48

⦁ 9w + 33 = 12w − 27
⦁ −2x + 7 = −21
⦁ 25 = 10y + 8

Answer 1

1.) 4p+8p+12=-48
12p=-48-12
12p=-60
p=-60/12
p=-5
2.) 9w+33=12w-27
33+27=12w-9w
60=3w
60/3=w
w=20
3.) -2x+7=-21
21+7=2x
28=2x
28/2=x
x=14
4.) 25=10y+8
25-8=10y
17=10y
17/10=y
y=1.7
