Question

1/7x +1/6y=3 and 1/2x_1/3y=5​

Answer 1

Answer:

Step-by-step explanation:

(1/7)x + (1/6)y = 3.........(i)

(1/2)x - (1/3)y = 5..........(ii)

multiplying equation (i) with 42 and equation (ii) with 6 on both sides we get

6x + 7y = 126........(iii)

3x - 2y = 30.........(iv)

now (iii)-2(iv)

11y= 66

y= 6

substituting in (iv)

3x = 42

x= 14
