Answer: 18x- 9

Step-by-step explanation:

1.) Put the numbers in their
correct lineup. 18 * x - 9

2. Add p
arentheses around 18 * x, secluding them away from the -9.
(18 * x) -9

3.) Remind yourself of
PEMDAS (Parentheses, Exponents, Multiplication, Division, Add, and Subtract). In this equation, 18 * x are in parentheses().
(18 * x)

4.)
Multiply 18 * x... Which equals 18x.

5. Equation should now look like :
18x - 9

6. You can't combine those two numbers because the coefficiant (The coefficiant is 18.) and the regular number (-9) are not equal.

8. Answer :
18x-9
