What is Y=6x-6 and - 3x-3y=-24

System of substitution

x = 2

y = 6

Step-by-step explanation:

y = 6x - 6

-3x - 3y = - 24

to find the value of x:

- 3x - 3 (6x - 6) = - 24

- 3x - 18x + 18 = - 24

-21x + 18 = - 24

-21x = - 42

x = 2

Now, to find the value of y:

(substitute x into the equation)

y = 6 x - 6

y = 6 (2) - 6

y = 12 - 6

y = 6
