Question

What is the solution to the equation 9-3x = 7?

Answer 1

x =
`(2)/(3)`

Explanation:

Given

9 - 3x = 7 ( subtract 9 from both sides )

- 3x = - 2 (divide both sides by - 3 )

x =
`(-2)/(-3)` =
`(2)/(3)`

Answer 2

`\huge{\boxed{x=(2)/(3)}}`

Add
`3x` on both sides.
`9=7+3x`

Subtract 7 from both sides.
`2=3x`

Divide both sides by 3.
`\boxed{(2)/(3)}=x`
