Answer:
x = 3, y = - 9
Step-by-step explanation:
5x + 5y = - 30...... (1)
2x - y = 15
-y = 15 - 2x
y = 2x - 15..... (2)
From equations (1) & (2)
5x + 5(2x - 15) = - 30
5x + 10x - 75 = - 30
15x = 75 - 30
15x = 45
x = 45/15
x = 3
Plug x = 3 in equation (2)
y = 2*3 - 15
y = 6 - 15
y = - 9
Therefore,
x = 3, y = - 9
or
(x, y) = (3, - 9)
Step-by-step explanation:
= (3x² + x + 8) + (x² - 9)
= (3 + 1)x² + x + (8 - 9)
= 4x² + x - 1
