Bridger Dalton · Answer 1

Y=6x-27 ... (1)

y=4x-17 ... (2)

By comparison

6x-27=4x-17

=> 2x=10 = > x=5

Substitute x=5 into (1)

y=6 (5) - 27=3

Check:

y=4 (5) - 17=3 as well.

Jenna Barton · Answer 2

Y=6x-27

y=4x-17

Subtracting the two equations, we get;

0=2x-10

2x=10

x=5

Replacing for x in equation 2;

y=4 (5) - 17

y=20-17

y=3
