Question

5x - 8y = - 4, 2x - 7y = 6​

Answer 1

Answer:

Answer is :-

Step-by-step explanation:

We are using elimination method here,

5x-8y=-4 is eq.1

2x-7y=6 is eq.2

Multiplying by 2 in eq.1 and 5 in eq.2, we get....

10x-16y=-8

10x-35y=30

Now cancelling 10x from both the equations by changing the signs we get....

19y=-38

y=-38/19

y=-2

Now putting y=-2 in eq.2 we get....

2x-7(-2)=6

2x+14=6

2x=6-14

2x=-8

x=-8/2

x=-4

So the value of x=-4 and y=-2
