7x + 3y = m

3y = m - 7x

y = (m - 7x) / 3


4( r + 3 ) = t

r + 3 = t / 4

r = ( t - 3 )/ 4


2x + b = w

2x = w- b

x = ( w - b ) / 2


x (1 + y) = 2

x = 2 / 1 +y

QUESTION 1

The given equation is


7x + 3y = m

We want to solve for y in the given equation.

First, we add

-7x
to both sides to obtain,


- 7x + 7 x+ 3y = m - 7x

This simplifies to,


3y = m - 7x

We divide both sides by 3 to get,


y = (m - 7x)/(3)

QUESTION 2

The given equation is,


4(r + 3) = t

We want to make

r
the subject.

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


(4(r + 3))/(4) = (t)/(4)

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


r + 3 = (t)/(4)

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


r + 3 + - 3 = (t)/(4) + - 3


r = (t)/(4) - 3


QUESTION 3

The given equation is


2x + b = w

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


2x + b - b = w - b

This simplifies to,


2x = w - b

We divide both sides by 2 to obtain,


(2x)/(2) = (w - b)/(2)

We cancel out common factors to get,


x = (w - b)/(2)

QUESTION 4

The given equation is


x(1 + y) = 2

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


(1 + y)
to obtain,


(x(1 + y))/(1 + y) = (2)/(1 + y)

We cancel out the common factors to obtain,


x = (2)/(1 + y)
