Question

the linear equation 3x-4y=10 has​

Answer 1

3x+4y=10---(1)

x−y=1---(2)

Substitute the values of first option x=2 and y=1

In equations (1) and (2)

3(2)+4(1)=10

6+4=10

10=10

x−y=1

2−1=1

1=1

Therefore, the first option satisfied the linear equations.

Likewise substitute the value of second option x=1,y=1

3x+4y=10

3(1)+4(1)=10

Similarly, check the options to satisfy the linear equation.

Here, the first option satisfied the linear equation.

The solution is (2,1).
