6y-8x=14

Replace y with y=x+5

6(x+5) – 8x= 14

Simplify

6x+30-8x=14

Add common factors

-2x+30=14

Subtract 30 from both side

-2x= -16

Divide both sides by -2

x=8

Now solve for y by replacing x with 8

y=8+5

y=13

Solution to the system of equations is (8,13)

6y-8x=14(1)

Y=x+5(2)

6y-8x=14(3) ×1

Y-x=5(4)×6

6y-8x=14

6y-6x=30

-2x=16

X=8

Put x into equation 1

6y-8x=14

6y-8(8)=14

6y-64=14

6y=14+64

6y=78

6y=78

Y=13
