Answer:
y = 3
Step-by-step explanation:
<em>*As seen in the photo, the fact that EF = GF and the bisector being there makes EH = HG.</em>
<u>5y + 10 = 28 - y</u>
<em>*Add y to both sides.</em>
6y + 10 = 28
<em>*Subtract 10 from both sides.</em>
6y = 18
<em>*Divide both sides by 6.</em>
y = 3
Hello!
x² + 6x + 1 = x - 3
Bring all terms to one side by subtracting x and adding 3:
x² + 6x - x + 1 + 3 = x - x - 3 + 3
x² + 5x + 4 = 0
Factor:
(x + 4)(x + 1) = 0
Set each factor to 0:
x + 4 = 0
x = -4
x + 1 = 0
x = -1
