`30x + 18 = 35 - 4x`

`x = (?)/(?)`
Enter the numbers that belong.​

Answer 1

`x = (1)/(2)`

Explanation:

`30x+18=35−4x`

First of all using the addition property add 4x to both sides

That's

`30x + 4x + 18 = 35 + 4x - 4x \\ 34x + 18 = 35`

Next using the subtraction property subtract 18 from both sides to make 34x stand alone

We have

`34x + 18 - 18 = 35 - 18 \\ 34x = 17`

Divide both sides by 34

That's

`(34x)/(34) = (17)/(34)`

We have the final answer as

`x = (1)/(2)`

Hope this helps you
