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.

5x + 3y = 8
y = −2x + 1

campbell_st · Answer

use substitution 

substitute y = -2x + 1 

into the 1st equation so that 

5x +3(-2x + 1) = 8

or 

5x - 6x + 3 = 8

solve for x, 

when you have x substitute into either equation to find y
