Question

3x + 4y = 31 & 5x - 3y = 13








​

Answer 1

Answer:

x = 5, y = 4

Step-by-step explanation:

3x + 4y = 31____(1)

5x - 3y = 13____(2)

Multiplying eq. 1 by 3 and eq. 2 by 4

9x + 12y = 93____(3)

20x - 12y = 52____(4)

Solving eq. 3 and 4

29x = 145

x = 145/29 = 5

Putting value of x = 5 in eq. 1

3x + 4y = 31

3×5 + 4y = 31

15 + 4y = 31

4y = 31 - 15

4y = 16

y = 16/4 = 4
