Answer: A and C
Step-by-step explanation:
Determine the answer by solving for x in each equation.
A. x + 4= 7 subtract 4 from both sides
-4 -4
x = 3
B. x/9 = 3 multiply both sides by 9
x=27
C. 5-x =2 subtract 5 from both sides
-5 -5
-1x = -3
x= 3
D. 8x = 32 divide both sides by 8
x = 4
E . x -10 = 7 Add 10 to both sides
+10 +10
x = 17
