Answer:
x = 3/2 y = 7
Step-by-step explanation:
We can subtract each side of equation 1 from each side of equation2 which gives us:
(2x + 4y) - (2x + y) = 31 - 10
3y = 21
y = 7
Substitute this value into one of the equations to find x:
2x + y = 10 (substitute 7 for y)
2x + (7) = 10 (subtract both sides by 7)
2x = 3 (divide both sides by 2)
x = 3/2
