Answer:
139/5
Stepbystep explaination:
Given :
→ 3x  2y = 5 ...(1)
→ 3y  2x = 3 ...(2)
First add these two equations, we get
→ x + y = 8 ...(3)
Second subtract these equations, we get
→ 5x  5y = 2
→ 5(x  y) = 2
→ x  y = 2/5 ...(4)
Now, add (3) and (4), we get
→ 2x = 8 + 2/5
→ 2x = 42/5
→ x = 21/5
Put this value in (3), we get
→ 21/5 + y = 8
→ y = 8  21/5
→ y = 19/5
Now,
→ m = 3x + 4y
Putting value of X and y.
→ m = 3(21/5) + 4(19/5)
→ m = 63/5 + 76/5
→ m = 139/5
