Question

Is x=-1 and y=3a solution of the system 7x+2y=1
5x+3y=14

Answer 1

Step-by-step explanation:

LHS:-

Putting the values of x and y

7x+2y

7(-1)+2(3)

-7+6

-1

MHS:-

Putting the values of x and y

15x+3y

15(-1)+3(3)

-15+9

-6

RHS:-

14

Here we can see that LHA is not equal to MHS and MHS is also not equal to RHS and LHS is not equal to RHS.
