Question

13. Solve the pair of linear equations x + 2y = -1 and 2x-3y = 12​

Answer 1

Answer:

x= 3

y= -2

Step-by-step explanation:

x+2y =-1 _________(1)

2x-3y = 12________(2)

2 multiple in equation 1

2x+4y= -2

subtraction with equation 2

2x-3y=12

2x+4y= -2

____________

-7y= 14

y=-2

then put value of y in equation 1

then x = 3
