(4x + 3)/(x + 1) + 2 = 8

(4x + 3)/(x + 1) + 2 = 8

Firstly minus the 2 from both sides

(4x + 3)/(x + 1) = 6

Then multiply both sides by the denominator (x + 1)

4x + 3 = 6(x + 1)

Expand the brackets.

4x + 3 = 6x + 6

Rearrange the equation so that the x's are on both sides. In this case, I have moved them to the right hand side as this is where the most amount of x's are.

3 - 6 = 6x - 4x

-3 = 2x

Divide by 2 to get the value of x.

-3/2 = x

x = -3/2
