Answer:
Step-by-step explanation:
D. D is the answer
Isolate the variable by putting numbers over the equal sign and multiplying/dividing. I'll do them for you
A. 7+3m=-29
3m=-29-7
3m=-36
M=-12
B. -5x+7=26
-5x=26-7
-5x=19
X=-3.8
C. 31=4-9y
31-4=-9y
27=-9y
-3=y
D. -52-3u=8
-3u=8+52
-3u=60
U=-20
E. 6-x=15
-x=15-6
-1x=9
X=-9
Hope this helps
