Answer:
(2, -5)
Step-by-step explanation:
x is defined by the first equation as x = -3y – 13. Substitute -3y – 13 for x in the second equation:
2( -3y – 13) + 2y = -6.
Performing the indicated multiplication, we get:
-6y - 26 + 2y = -6
Combining like terms results in:
-4y = 20, so that y = -5
Using the first equation, we find x for y = -5:
x = -3(-5) - 13 = 2
The solution is thus (2, -5) (Answer C)
Answer:
x=2 & y=-5, so the answer is C
Step-by-step explanation:
x = -3y-13 ------(1)
2x + 2y = -6 ---------(2)
sub(1)into(2)
(2)=> 2(-3y-13) + 2y = -6
-6y - 26 + 2y = -6
-4y = 20
y = -5
sub y=-5 into(1)
(1)=> x = -3(-5) - 13
= 15 - 13
= 2
