Answer:
Multiply the first equation by 4.
Step-by-step explanation:
4(x+y=3) which gives
4x+4y=12
and
4x-y=7
Then subtract the two equations and the x variable will be eliminated.
Step-by-step explanation:
3/8 and 11/15
LCM = 30
3/8x4 and 11/15x2
12/30 and 22/30
22/30-12/30
=10/30
The difference is 10/30
The larger sum is 11/15
