Answer:
x=21
Step-by-step explanation:
![2(2x+3)=90\\2x+3=45\\2x=42\\x=21](https://tex.z-dn.net/?f=2%282x%2B3%29%3D90%5C%5C2x%2B3%3D45%5C%5C2x%3D42%5C%5Cx%3D21)
Answer:
x^2 +9x +1
Step-by-step explanation:
(5x-2+3x^2)+(4x+3)
Writing in decreasing order so we can combine like terms
3x^2 +5x+4x-2+3
Add and subtract like terms
3x^2 +9x +1
<h3><u>Question</u><u>:</u></h3>
Complete the solution of the equation. find the value of y when x = -14.
<h3><u>Solution</u><u>:</u></h3>
To find the value of y we need to plug and substitute the equation if x = -14.
- -2x - 3y = 49
- -2(-14) - 3y = 49
- 28 - 3y = 49
- -3y = 49 - 28
- -3y = 21/-3
- y = -7
<h3><u>Answ</u><u>er</u><u>:</u></h3>
- The value of y is <u>-</u><u>7</u>
