(x - 39) + (x + 61) = x - 39 + x + 61 = (x + x) + (-39 + 61) = 2x + 22
Answer:
y=(7±√89)/-4
Step-by-step explanation:
y=(-b±√b^2 -4ac)/2a
Rewrite given equation in quadratic form so it is -2y-7y+5=0
Then, in formula, sub -2 for a, -7 for b, and 5 for c
y=-(-7)±√(-7)^2 -4(-2)(5)/2(-2)
When you multiply that out you get
7±√49-(-40)/-4
The next step is the answer given above
If you need the answer not in sq rt form, it is y=-4.1085 and y=0.0608
