Answer:
x = -1
y = 1
Step-by-step explanation:
x + 2y = 1 (Multiply this by -2)
2x + 5y = 3
-2x - 4y = -2
2x + 5y = 3
y = 1
x + 2y = 1
x + 2(1) = 1
x + 2 = 1
x = 1 - 2
x = -1
Factor:
9x^2 - 64
= (3x)^2 - 8^2
= (3x + 8)(3x - 8)
If you want to solve it, let the equation equal zero
(3x + 8)(3x - 8) = 0
3x + 8 = 0 ; x = -8/3
3x - 8 = 0 ; x = 8/3
Solutions: x = -8/3 and x = 8/3
