Answer 2

Answer:

Question:-

Check whether (1,-2) is a solution of 3x-y=6 ?

Solution:-

Put value of x is 1 and y is (-2)

To prove if this is a solution of this equation or not. We need to prove LHS = RHS

LHS RHS

$3 \times 1 - ( - 2) = 6$

$3 + 2 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 6$

$5 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 6$

LHS not equal to RHS so this is not a solution.
