Answer:

[tex](2,3)[/tex]

Step-by-step explanation:

The given equations are:

1st: -3x=42-16y

2nd: 14x=76-16y

Subtract the first equation from the second one:

14x--3x=76-42-16y--16y

14x+3x=34-16y+16y

17x=34

[tex]x=\frac{34}{17}=2[/tex]

We plug in x-value into the second equation to get:

14(2)=76-16y

14x=76-32

28-76=-16y

-48=-16y

Divide both sides by -16

y=3
