solve the following system of equations:

Question

2x + 5y = 10

x + 2y = 3

Answer 1

Solving by elimination: (Multiply the entire second equation by 2, then subtract it from the 1st to eliminate x)

(2x + 5y = 10)

-( 2x + 4y = 6)

___________

y = 4. Substitute 4 for y in either original equation to get x = -5
