Rearrange the equation y = 3(x+1)/4, making x the subject.

Firstly, before we even approach the bracket containing the x term, we want to deal with the fraction. The first step should be multiplying by 4 to cancel out the denominator on the right. This leaves us with 4y = 3(x+1). In the second step, we divide by 3 which cancels out the 3 on the right hand side and therefore allow us to access the x term in the bracket. We then have 4y/3 = x+1. The last step is to subtract the 1 on the right hand side. This leaves us with 4y/3 - 1 = x.
