Plugging into the Given Formula the value of y:
Multiply the left side:
Add 14 to both sides to get:
Divide both sides by 8 and we get:
Therefore, x=7 and the proof is complete
= 8y^2 - 32y + 3y^2 + 6y
= 11y^2 - 26y
Well, you do 36-17 and your answer is 19 so x=19 have a good day!
A=3/12 B=15/3 Im sorry if this is incorrect but all i did was multiply them by .75 since 3/4 equals that.
