Answer:
4 =x
Step-by-step explanation:
-3(x+4) = 4(x-10)
Distribute
-3x-12 = 4x - 40
Add 3x to each side
-3x -12 +3x = 4x +3x-40
-12 = 7x-40
Add 40 to each side
-12 +40 = 7x - 40+40
28 = 7x
Divide each side by 7
28/7 = 7x/7
4 =x
Answer:
x=4
Step-by-step explanation:
-3(x+4)=4(x-10)
-3x-12=4x-40
+3x . +3x
-12=7x-40
+40 . +40
(28)/7=(7x)/7
