Question

Provide an example that uses the elimination method to solve two linear equations.

Answer 1

4x - 2y = 10
3x + 4y = 13

get the coefficients in y column equal by multiplying top equation by 2
8x-4y=20
3x+4y=13

add each column
11x +0y = 33
solve for x
11x=33
x=33/11 =3

Then substitute 3 in for x in one of original equations
4x-2y =10
4(3) -2y =10
12-2y=10
-2y = -2
y=-2/-2 = 1

solution is x=3,y=1
