Question

How many solutions does the equation have?



A.
one solution

B.
infinite solutions

C.
no solution

Answer 1

Let's solve your equation step-by-step.

6−a=
1
3
(9a−18)
Step 1: Simplify both sides of the equation.

−a+6=3a−6

Step 2: Subtract 3a from both sides.

−a+6−3a=3a−6−3a

−4a+6=−6

Step 3: Subtract 6 from both sides.

−4a+6−6=−6−6

−4a=−12

Step 4: Divide both sides by -4.


−4a
−4
=
−12
−4

a=3



Answer:

a=3
one solution
