Question

] Use the Substitution Method to solve the following system of equations.
2x + y = 3
-3x + 4y = 1

Answer 1

let y = 3 - 2x

then substituting into the 2nd equation

-3x + 4( 3 - 2x) = 1

or

-3x + 12 - 8x = 1

-11x + 12 = 1

solve for x....

when you have a value for x, substitute it into the 1st equation to find y

this will be the ordered pair solution
