Question

$- 4x + 7 = 11$I need help with this question for math

Answer 1

Answer: x = -1

Explanation:

The expression we have is:

$-4x+7=11$

To solve for x we do the following.

Step 1: substract 7 from both sides of the equation

$-4x+7-7=11-7$

So that the +7 and -7 on the left side are cancelled

$-4x=4$

Step 2: Divide both sides of the equation by -4:

$\frac{-4x}{-4}=\frac{4}{-4}$

in the left side we are left with x, and in the right side with -1:

$x=-1$
