Answer 1

Can you specify?

Answer 2

How many solutions does the equation have?

6 - a = 1/3(9a - 18)

A.
one solution

B.
infinite solutions

C.
no solution

Answer 3

Let's simplify:
6 - a = 1/3(9a - 18)
6 - a = 1/3 x 9a - 1/3 x 18
6 - a = 3a - 6

Rearrange:
12 = 4a
a = 3

One solution
A

Answer 4

I'm confused with what you are doing..it makes no sense to me.

Answer 5

Okay. So the first step is simplifying the equation. We only need to look at the right hand side (1/3(9a - 18)) as the left hand side is already in it's simplest form.

The first step to simplify 1/3(9a - 18) is to multiply out the brackets. To do this, the number outside the brackets (1/3) has to be multiplied by each number inside the brackets (9a) and (-18)


Good so far?
