Question

x/3 + y/12 = 7/2

x/6 - y/8 = 6/8​

Answer 1

Answer:

1 equation's answer is x+y=21/2

Step-by-step explanation:

x/3+y/12=7/2

lcm of 3 and 12 is 12

4x+y/12=7/2

4x+y=7/2*12

4x+y=42

x+y=42/4

x+y=21/2 answer

Answer 2

Step-by-step explanation:

1)x/3+y/12=7/2

4×x÷3×4+y/12=7×6/2×6

4x/12+y/12=42/12

4x+y=42

2) x/6-y/8=6/8

(x×4/6×4)-(y×3/8×3)=6×3/8×3

4x/24-3y/24=18/24

4x-3y=18
