Question

Simplify equations HELP NOW!!

Answer 1

`(1)/(5) (2x+10)=4`
`x=5`

`(1)/(3) (3x+9)=9`
`x=6`

Explanation:

`(1)/(5) (2x+10)=4`

Multiply both sides of the equation by 5.

5 ·
`(1)/(5)` ·
`(2x+10)=` 5 · 4

Simplify both sides of the equation.

`2x+10=20`

Subtract 10 from both sides of the equation.

`2x=10`

Divide each term by 2 and simplify.

`x=5`

--------------------------------------------------------------------

`(1)/(3) (3x+9)=9`

Substitute x for 6

`(1)/(3) (3(6)+9)=9`

Multiply 3 · 6

`(1)/(3) ((18)+9)=9`

Add 18 + 9

`(1)/(3) (27)=9`

Divide
`(1)/(3)` ÷ 27

9 = 9
