Question

Solve the equations: 5x - 4y + 2 = 0; 2x + 3y -13 = 0.

Answer 1

Answer:

x = 2

y = 3

Step-by-step explanation:

5x - 4y + 2 = 0 ----------------- (1)

2x + 3y - 13 = 0 ----------------(2)

multiply

     equation (1) * 3 and equation (2) * 4

here we get

       15x - 12y + 6 = 0

       8x  + 12y - 52 = 0

_________________________

      23x +0y - 46 = 0

23x - 46 = 0

23x = 46

x = 2

x in equation (2)

2 * 2 + 3y - 13 = 0

4 + 3y - 13 = 0

3y = 13 - 4

3y = 9

y = 9/3

y = 3
