Question

Please help!!!!!
Solve the system by substitution:
y=3x-1
y=-4x+20
and can you show my how to do it please?

Answer 1

y=3x-1 <--- y= 2x
y=-4x+20 <--- y= 16x
here is how you do it: just take the x off of the 3 and the x off of the -44 to make it -4 + 20 and 3 - 1 then just do it like you normaly would and put the x's at the end of the problem/answer.
