Question

Given p(x) = x+7/3
if p(x) = 13, find x.

Answer 1

x =
`(32)/(3)`

Explanation:

We know that p(x) = 13. Thus, substitute 13 for the "p(x)" in the equation. Then, isolate x by subtracting both sides by
`(7)/(3)`:

`p(x) = x + (7)/(3)\\13 = x + (7)/(3) \\13 - (7)/(3) = x \\(39)/(3)- (7)/(3) = x \\(32)/(3) = x`

Thus, x =
`(32)/(3)`.
