Question

2 1/3 −1.5x=12.3
Solve for x

Answer 1

x =
`-6.6\overline{4}`

Explanation:

Subtract 2 1/3 from both sides of the equation. 2 1/3 is the same as 2.3333... in decimal form. Now you have:

• -1.5x = 9.966667

Divide both sides by -1.5 to isolate and solve for x.

• x = -6.6444...

To show a repeating decimal you would put a line over the repeated number. In this case the line would be over the number 4.

The final answer is x =
`-6.6\overline{4}`.
