Question

Can someone show me how to do this I'm a little confused....please, and thank you :)
Solve the following system of equations using the substitution method and show all of your work.

5x + 3y = 8
y = −2x + 1

Answer 1

so you have y = something
so sub y = something into the first equation

Answer 2

5x + 3y = 8
5x + 3(-2x + 1) = 8

Answer 3

okay so then I distribute ?

Answer 4

5x-6x+3=8.....is that wrong?

Answer 5

so use that to work out what x =

and from that work out what y =
