I would clean them up first
1st times 10 ----> 4x + 5y = 30
2nd times 6 ----> 3x - y = 12
now multiply that last one by 5
15x - 5y = 60
4x + 5y = 30
Add them:
19x = 90
x = 90/19
y = 3x-12 = 42/19
Solve using the elimination method.
2x/5 + y/2 = 3
x/2-y/6=2
Please and Thank you

multiply the first equation by 1/3
2x/15 + y/6 = 1 new first
x/2-y/6=2 second
then add equations
2x/15+x/2=3 then solve for x.
2x/15 + y/6 = 1 new first
x/2-y/6=2 second
then add equations
2x/15+x/2=3 then solve for x.
