Question

Use the elimination method to solve the given system of equations.
2x +y=14
3x -y=1
a.(2,10)
b.(13,-12)
c.(3,8)
d.(5,4)

Answer 1

add bouth equations

Answer 2

Pick an equation, solve it for one vbl, subst in the other eqn.
For example, second eqn produces y=3x-1.
Subst into other eqn to get: 2x + (3x-1) = 14.
So 5x-1 = 14, 5x=15, x=3.
Subst x=3 into either eqn to get y=8.
Solution is (c), (3,8).
Done.
