Whats y=6x-18

y=4x-10

4x-10=6x-18

4x=6x-8

-2x=-8

x=4

y=6 (4) - 18

y=24-18

y=6

1.) You add 18 to both sides 2.) You add 10 to both sides

y = 6x - 18 y = 4x - 10

+18 + 18 + 10 + 10

then you divide by 6 then you divide by 4

18 = 6x 10 = 4x

/6 / 6 / 4 / 4

where x is equal to 3 where x is equal to 2.5

x = 3 x = 2.5
