Question

Eliminiation Please!

0.5x + 0.5y = -2

x - 0.25y = 6

Answer 1

x = 4; y = -8

Explanation:

0.5x + 0.5y = -2

x - 0.25y = 6

Rewrite the first equation. Multiply both sides of the second equation by 2 and write below the first equation. then add the equations.

0.5x + 0.5y = -2

+ 2x - 0.5y = 12

---------------------------

2.5x = 10

x = 4

x - 0.25y = 6

4 - 0.25y = 6

-0.25y = 2

y = -2/0.25

y = -8

x = 4; y = -8
