Question

Solve the following system and show all of your work.
x − 2y = 14
x + 3y = 9

Answer 1

subtract equation 1 from 2
we get
5y = -5
then put the value of y in either equation

Answer 2

Hint:
Substitution method.
Solve for x in the first equation:
x = 2y + 14
^Substitute this in for the value of x in the second equation.
x + 3y = 9
(2y + 14) + 3y = 9

Combine like terms and solve for y. Then substitute the value of y in either equation to find x.
