Solve the following system of equations:
2x + 3y = 40
-2x + 2y = 20
We can add these equations to get a new equation. Then we can solve for y:
0 + 5y = 60
5y = 60
y = 12
2x + 3y = 40, plug in y = 12 and solve for x:
2x + 36 = 40
2x = 4
x = 2

Answer:
(x +5)^2 = -2
Step-by-step explanation:
We can subtract the constant to get ...
x^2 +10x = -27
Then add the square of half the x-coefficient:
x^2 +10x +5^2 = -27 +5^2
(x +5)^2 = -2 . . . . . . write as a square
