Ответ:
2=x
Step-by-step explanation:
8(4-x)=7x+2
Distribute
32 - 8x = 7x+2
Add 8x to each side
32 - 8x+8x = 7x+8x+2
32 = 15x+2
Subtract 2 from each side
32-2 = 15x+2-2
30 = 15x
Divide each side by 15
30/15 = 15x/15
2 =x
Ответ:
First, let's subtract z from each side:
z-m-z = z+bx-z
-m=bx
Then, to find x, you divide both sides by b to get the variable x alone on a side, and the others on another side:
-m/b = bx/b
-m/b = x
So, in z-m = z+bx, x = -m/b
Hope this Helps! :)
