<u><em>When x = -2</em></u>, f(x) = -7(-2) + 3 = 14 + 3
<u><em>x = 17</em></u>
<u><em>When x = 5</em></u>, f(x) = -7(5) + 3 = -35 + 3
<u><em>x = -32</em></u>
All you have to do to solve the function is substitute the value of x into the equation.
So first you would multiply 18 and 20% and with that answer you have to dive by 100 because that's the whole for a percent number, your answer should be $3.60
X=6.62
x+1.91=8.53
you have to subtract 1.91 from both sides of the equation to get x alone on one side of the equation. Once you do that you end up with x on one side and 6.62 on the other side, giving you the answer to x.
