Question

What is the value of x in the equation 2x + 3y = 36, when y = 6?
8
9
027
36

Answer 1

x = 9.

Explanation:

The first step I did was replace y with 6.

`2x+3\cdot \:6=36`

I multiplied 3*6 next.

`2x+18=36`

Then I subtracted 18 from both sides of the equation.

`2x+18-18=36-18`

After, I simplified the equation.

2x=18

Divided the both by 2 and then simplified again to get...

`(2x)/(2)=(18)/(2)`

`x=9`

So
`x=9`.
