Question

10x-9y=24

y= x-2
find x and y

Answer 1

x=6 y=4

Explanation:

Substitute x-2 in for y: 10x-9(x-2)=24

Distribute: 10x-9x+18=24

Subtract 10x-9x=1x

Subtract 18 from both sides

x=6

Substitute 6 for x

y=6-2

y=4

x=6 y=4

Answer 2

x=6,y=4

Explanation:

10x-9(x-2)=24

10x-9x+18=24

x=24-18

x=6

sub x

y=6-2

y=4
