3/2x-7=-11

We move all terms to the left:

3/2x-7-(-11)=0

Domain of the equation: 2x!=0

x!=0/2

x!=0

x∈R

We add all the numbers together, and all the variables

3/2x+4=0

We multiply all the terms by the denominator

4*2x+3=0

Wy multiply elements

8x+3=0

We move all terms containing x to the left, all other terms to the right

8x=-3

x=-3/8

-3/4 + (-3/4)<br><img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%203%7D%7B4%7D%20%20%2B%20%20%5Cfrac%7B%20-%203%7D%7B4%7D%20

Firstly, since these two fractions have the same denominator, add the numerators up: $\frac{-6}{4}$

While it appears that the answer is -6/4, you can further simplify it by dividing the numerator and denominator by 2: $-\frac{6}{4}\div\frac{2}{2}=-\frac{3}{2}$

<u>Your answer is $-\frac{3}{2}$ </u>
