I SERIOUSLY need help!

Solve the linear system by using substitution.
x=6-4y
2x-3y=1

Explanation too, please!
Please and thanks!
Answered by Reiny
very very easy

sub x = 6-4y into
2x - 3y = 1
2(6-4y) - 3y = 1
12 - 8y - 3y = 1
-11y = -11
y = 1

then x = 6 - 4(1) = 2

Thank you, but:
How did you go from 12-8y-3y to -11y?
Answered by Reiny
12 - 8y - 3y = 1
12 - 11y = 1 , that should be clear
12 <b>-12</b> - 11y = 1 <b>-12</b>
-11y = -11
divide by -11
y = 1
