Question

If 3x - 2y = 5 and 3y - 2x = 3 then find m if m = 3x + 4y

Answer 1

here is your answer mate

Answer 2

Answer:

139/5

Step-by-step 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
