Question

Solve the pair of equations: 2 + 3 = 13 5 - 4 = -2Solve the pair of equations: 2 + 3 = 13 5 - 4 = -2

Answer 1

Step-by-step explanation:

2x+3y=13

5x-4y=-2

first we equal one coefficient like x and y

Now

2x+3y=13 *4

5x-4y=-2 *3

8x+12y=52 (1)

15x-12y=-6 (2)

23x=46

x=46/23

x=2

Now put the value of x in 1

8*2+12y=52

16+12y=52

12y=52-16

12y=36

y=36/12

y=3
