Answer:
The solution to the equation is
x = 4
Step-by-step explanation:
Given the equation:
-2(x - 4) = 7x - 28
To solve for x,
Expand the bracket on the left-hand side
-2x + 8 = 7x - 28
Add 2x to both sides of the equation
-2x + 8 + 2x = 7x - 28 + 2x
8 = 9x - 28
Add 28 to both sides
8 + 28 = 9x - 28 + 28
36 = 9x
Divide both sides by 9
36/9 = 9x/9
4 = x
Thererfore, x = 4
