Question

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

Answer 1

First of all we will solve for x and then with the value of x we will find the answer to the second question...

$\tt \: 9x + 12 = 48$

$\tt \: 9x = 48 - 12$

$\tt \: 9x = 36$

$\boxed{ \bf \: x = 4}$

Now,

$\sf \: x - 10 \\ \sf \: 4 - 10 \\ \sf \: - 6$

Answer 2

Answer:

x - 10 = -6

Step-by-step 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.
