Question

If 9x + 12 = 48 what is x-10?

Answer 1

i)

9x + 12 = 48

or,9x=48-12

or,9x=36

or,x=36/9

or,x=4

Thus,the value of x is 4.

ii)

x-10

=4-10(Putting x as 4)

=-6

Answer 2

x - 10 = -6

Explanation:

9x + 12 = 48

Subtract 12 from both sides.

9x + 12 = 48

- 12 - 12

+ 12 and - 12 cancel out. 48 - 12 is 36.

9x = 36

Divide 9 from both sides.

9x = 36

÷ 9 ÷ 9

9 ÷ 9 cancels out. x is left. 36 ÷ 9 is 4.

x = 4

Knowing x = 4, solve the equation.

x - 10 = ?

Plug in 4.

4 - 10 = -6

4 - 10 equals -6. This is your answer.
