Question

how do I solve the y=x-9

3y-2x=36
using the substitution method ?

Answer 1

3(x-9) - 2x = 36
3x - 27 - 2x = 36
3x - 2x = 36 - 27
3x - 2x = 9
x = 9

Is that okay?(: Do you need to find y?

Answer 2

yes

Answer 3

To find y, sub. the value of x into the equation y = x - 9

x = 9
y = x - 9
y = 9 - 9
y = 0
