4. What is the solution of the system of equations?
ations-y + 3x = 6
y = -6x + 12
F. (-2,0)
H. (2,0)
G. (0, -2)
L. (0,2)

Step-by-step explanation:

y = -6x + 12 1

-y + 3x = 6 2

from equation  equation 1

y = -6x + 12 1

put  y = -6x + 12

in equation 2

-( -6x + 12) + 3x = 6

6x - 12 + 3x = 6

6x - 3x = 6 + 12

3x = 18

divide both sides by 3

x = 6

to find y now

put x = 6 in equation  1

y = -6x + 12 1

y = -6(6) + 12

y -36 + 12

y = -24

therefore x = 6 y = -24

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14
