Answer:

x = 11.2

Step-by-step explanation:

-5x - 12y = -8  

5x + 2y = 48

you can combine all like terms from both equations together:

0x-10y=40

simplified:

-10y=40

y=-4

now you plug in the value of y into either equation:

5x+2(-4)=48

simplify

5x-8=48

add 8

5x=56

divide by 5

x=56/5=11.2
