Detailed Solution

Given equations are,

2 x + 3 y = 46 ...... (1) 3 x + 5 y = 74 ...... (2)

Multiplying equation 1 by 3 and equation 2 by 2, we get,

6 x + 9 y = 138 ...... 3 6 x + 10 y = 148 ...... (4)

Subtracting equation 4 from equation 3, we get,

6 x + 9 y = 138 6 x + 10 y = 148 (-)    (-)           (-) − − − − − − − − − − − − y = − 10 − − − − − − − − − − − ⇒ y = 10

Substituting the value of y = 10 in equation 2 to find the value of x, we get,

3 x + 5 y = 74 ⇒ 3 x + 510 = 74 ⇒ 3 x + 50 = 74 ⇒ 3 x = 74 − 50 ⇒ 3 x = 24 ⇒ x = 243 ⇒ x = 8

Hence, the solution of the given system of equations is

x = 8

and y = 10.
Thus, option 3 is correct.
