7x + 3y = m solve for y 4(r + 3) = t solve for r 2x + b = w solve for x x(1 + y) = 2 solve for x

QUESTION 1

The given equation is



We want to solve for y in the given equation.

First, we add

to both sides to obtain,



This simplifies to,



We divide both sides by 3 to get,



QUESTION 2

The given equation is,



We want to make

the subject.

We first of all divide both sides by 4 to get,



We now cancel out the common factor on the left hand side to get,



Let us add -3 to both sides of the equation to obtain,





QUESTION 3

The given equation is



We want to solve for x, so we subtract b from both sides to obtain,



This simplifies to,



We divide both sides by 2 to obtain,



We cancel out common factors to get,



QUESTION 4

The given equation is



We want to solve for x, so we divide both sides by


to obtain,



We cancel out the common factors to obtain,
