Question

0.05x+0.25y=11 and 0.15x+0.05y=12 solve by elimination

Answer 1

x = 70 and y = 30. multiply the entire second equation by 5 and subtract it from the first equation, then solve for x, plug in value for x into whichever equation you want to solve for y.

Answer 2

first multiply the first equation by 3 so that the x term will be cancelled out then subtract the 2 equations

Answer 3

Traile can you check your math when subtracting the first two equations?

Answer 4

(0.05x+0.25y=11 )3
0.15x+0.05y=12

0.15x+0.75y=33

0.15x+0.05y=12
-0.15x-0.75y=-33
-0.7y=-21
y=30

0.15x+0.05(30)=12
x=70
