Question

Please help. I will fan and give medal to whoever succeeds in assisting me.

Part 1: Decide whether you would use the graphing, substitution, or elimination method to solve the following system of equations. Explain, in complete sentences, why you chose that method.
Part 2: Solve the following system of equations and show all of your work.

4x + 3y = -1
3x + y = 3

Answer 1

use substitute as the 2nd equation has a single y

rewriting the 2nd equation with y as the subject gives

y = 3 - 3x

substitute this into the 1st equation and you will have an equation
in terms of x only

4x + 3(3 - 3x) = -1

just distribute and then collect like terms and solve for x.

when you have x, substitute into the 2nd equation to find y.

Answer 2

Got it, thanks.
