Solve his problem for X and Y​
Verizon [17]

<em><u>Answer:</u></em>

<em><u>y = 5, 3; x = 171, 155</u></em>

<em><u>Step-by-step explanation:</u></em>

8y - 15 = y^2

y^2-8y+15=0

y^2-3y-5y+15=0

y(y-3)-5(y-3)=0

(y-5)(y-3)=0

y can be 5 or 3.

x = 180 - (8y - 15)

x = 180 - (8(3)-15)

x = 180 - 9

x = 171

OR

x = 180 - (8(5) - 15)

x = 180 - 25

x = 155
