Because x+7=0 is -7
So substitute the number (-7) to (x^2+4x-24)
Answer:
x<em> </em>+ 2y - 3.5
Step-by-step explanation:
<u>Because the only operation to be used is addition, the parentheses can be taken away:</u>
(x - 5) + (2y - 3.5) + (-x + 5)
x - 5 + 2y - 3.5 + -x + 5
<u>Addition of negative numbers is subtraction:</u>
<u />x - 5 + 2y - 3.5 + -x + 5
x - 5 + 2y - 3.5 - x + 5
<u>Combine like terms to find the furthest simplification of the equation:</u>
<u />x - 5 + 2y - 3.5 - x + 5
x - 5 + 2y - 3.5 + 5
x + 2y - 3.5
<u>Finally, simplify the coefficient of x:</u>
x + 2y - 3.5
x + 2y - 3.5
(x - 5) + (2y - 3.5) + (-x + 5) =<u> </u><u>x + 2y - 3.5</u>
