Step-by-step explanation:

Hey, there!!

Let's solve it simply.

Given,

11 - 13x - 7 - 2x = 7

Simplify the like terms.

11 - 7 - 13x - 2x = 7

4 - 15x = 7.

shifting 4 in right side.

-15x =7-4

-15x = 3

Divide 3 by -15.

x =  \frac{3 }{ - 15}

Therefore, x = (-3/15) or (-1/5).

Step-by-step explanation:

First you add 4 on both sides

X^2=0

Then you take square on both sides

X=+- the square root of 4

Simplify that
