Step-by-step explanation:

4x + 3y = 12

4x + 3y - 12 = 0 (eqn no. 1)

2x + 4y = 11

2x + 4y - 11 = 0 (eqn no. 2)

(equal the value of x or y in both the eqns)

multiplying eqn no. 2 by 2)

2(2x + 4y - 11) = 0

4x + 8y - 22 = 0 (eqn no. 3)

(now the value of x is same in both the eqns)

subtracting eqn no. 3 by eqn no. 1

(4x + 8y - 22) - (4x + 3y - 12) = 0

4x + 8y - 22 - 4x - 3y + 12 = 0

(4x - 4x) + (8y - 3y) + (-22 + 12) = 0

5y - 10 = 0

5y = 10

y = 10/5

y = 2

now putting the value of y in eqn no. 1

4x + 3y = 12

4x + 3(2) = 12

4x + 6 = 12

4x = 12 - 6

4x = 6

x = 6/4

x = 3/2

hence, the value of x = 3/2 and y = 2
