Question

What is the value of x in the y = 2/3x + 5 when y=7?

Answer 1

x=3

Explanation:

To start all you need to do is replace
`y` with 7 to get
`7=(2)/(3)x+5`

Then, you need to isolate x on the right side of the equation, starting with subtracting 5 on both sides to get
`2=(2)/(3)x`

Finally, you divide both sides by
`(2)/(3)`. You divide fractions by multiplying the reciprocal like so
`(2)/(1) *(3)/(2) =x` to get
`(6)/(2) =x`. This means that x=3

Answer 2

x = 3

Explanation:

y = 2/3 x + 5; y = 7

7 = (2/3)x + 5

2 = (2/3)x

x = 2 * 3/2

x = 3
