Question

The pair of linear equations 6x-7y=1 and 3x-4y =5 has​

Answer 1

Answer:

x = -31/3, y = -9

Step-by-step explanation:

6x-7y=1

[3x-4y =5]*2 => 6x - 8y = 10

6x - 7y = 1

6x - 8y = 10

- + -

------------------

1y = -9, y = -9

put the value of y in first equation

6x - 7y = 1

6x - 7(-9) = 1

6x + 63 = 1

6x = -62

x = -62/6

x = -31/3

Answer 2

Answer:

x=-31/3 and y=-9

Given-The two equations with two variables.

Step1. let the first equation as 1

6x-7y=1   (1)

Step2. Multiply the given 2nd equation by2 we get

[3x-4y =5]*2 => 6x - 8y = 10

Step3. Now solve the both equations by elimination method-

6x - 7y = 1

6x - 8y = 10

- + -

-----------------

1y = -9, y = -9

Step4-put the value of y in first equation

6x - 7y = 1

6x - 7(-9) = 1

6x + 63 = 1

6x = -62

x = -62/6

x = -31/3
