Question

5х +6y = 7
3х + 2y = 5
Solve the following simultaneously linear equations by substitution method .​

Answer 1

Answer:

5x+6y=7(1)

3x+2y=5*3(2).

9x+6y=15

5x+6y=7

9x-5x+6y-6y=15-7

4x=12

x=3

put out of y

5*3+6y=7

6y=7-15

y=-8/6

=-4/3

Answer 2

Answer:

1.x=-1,y=2

2.x=1,y=1

Step-by-step explanation:

1. (5 ✖ -1)+(6 ✖ 2)

-5+12=7

2.(3 ✖ 1)+(2 ✖ 1)

3+2=5

I hope it will help you.

Please follow me and mark as brilliant and click the thanks option too.

Sorry I know my answer is wrong. But I was not aware about the substitution method because I am in 9th class. So according to my level I gave the answer. But still you thanks me. Thanks for that.....
