Answer 2

Question

• a + 3x = b + c make x the subject

Solution

» a + 3x = b + c

» 3x = b + c - a

» x = b + c - a/3

How?

In this question, we have to make x as the subject. For making x as the subject we would have to transfer a and 3 to the other side. When +a is transferred to the other side it will become -a and ×3 will become ÷3 .Like this:-

a + 3x = b + c = 3x = b + c - a = x = b + c - a/3

Question

• ax = b + c

Solution

» ax = b + c

» x = b + c - a

How ?

In the question, ax = b + c. We have to change it and make x the subject. So for making x the subject we have to transfer a to the other side. Than +a will become -a and form an equation like this :- x = b + c - a
