I need help now please, I can’t figure this out

B. 1,4

Step-by-step explanation:

1. substitute 4x for y in the second equation since we know y=4x(to find x)

6x-4(4x)=-10

2.solve for x

6x-4(4x)=-10

-4•4x=-16x

6x-16x=-10

6x-16x=-10x

-10x=-10

-10x/-10=-10/-10

x=1

3.substitute 1 for x in either equation(since x=1)to find y

y=4(1)

y=4

x,y=1,4
