Question

Solve the system below, choose the x and y answers from the list below.

6x + 5y = 4
-6x + 7y = 20
OX= -1
O y = 2
OX= -2
y = 1
OX= 1
O y = -2
ASAP

Answer 1

y=2, x=-1

Explanation:

We can add the two equations together to eliminate x:

6x+5y+(-6x)+7y=4+20

12y=24

y=2

We plug y into the first equation and get

6x+5(2)=4

6x+10=4

6x=-6

x=-1
