Answer:
The answer is option C.
The answer is option
Explanation:
5x + 2y = - 15 ......... 1
x - 4y = - 3 ........ 2
Make x the subject in the second equation and substitute it into the first equation
That's
x = 4y - 3
5(4y - 3) + 2y = - 15
20y - 15 + 2y = - 15
22y = - 15 + 15
22y = 0
Divide both sides by 22
y = 0
Substitute y = 0 into x = 4y - 3
That's
x = 4(0) - 3
x = - 3
x = - 3 y = 0
( - 3 , 0)
Hope this helps you
