Question

What is x? PLEASE HELP ME ITS ALMOST BEEN AN HOUR

Answer 1

Explanation:

The objective here is to understand functions and manipulating them.

We know that f(x)=3 j(x)=-x+5 g(x)=x-5 and h(x)=2(2x+3). We subsitue those values in for the expression.

`3 - ( - x + 5) + x - 5 = 2(2x - 3)`

`3 + x - 5 + x - 5 = 2(2x - 3)`

`2x - 7 = 2(2x - 3)`

`2x -7= 4x - 6`

`2x -1 = 4x`

`-1 = 2x`

[tex]x =-0.5
