Answer:x=1 & y=6 or (1,6)Step-by-step explanation:3x-x+5=7 Substitute the 2nd equation in for y

2x+5=7 Do 3x-x to get 2x

2x=2 Subtract 5 from both sides

x=1 Divide 2 from both sides

y=1+5 Insert 1 as x

y=6 Add 1+5 to solve for y

Hope this helped!

X=3, Y=9

X+Y=12

Y=X+6

X+X+6=12

2X=6

X=3

Y=3+6=9
