Question

7x-8y=22;5x-3y=13 stimultaneous equations​

Answer 1

Step-by-step explanation:

7x-8y=22

5x-3y=13

multiplying 1st equation with 5 and 2nd equation with 7

35x-40y=110

35x-21y=91

subtracting both equations we get

-19y=19

y = -1

substituting y value

5x-3(-1)=13

5x+3=13

5x=10

x=2
