1. Check whether

$(5,-1)$ is a solution of the simultaneous equations

$x - 2y = 7$ and

$2x + 3y = 7$ .

Proof:

$x - 2y = 7$ ---- (

$1$ )

$2x + 3y = 7$ ---- (

$2$ )

Substitute

$x =$ and

$y =$ in equations (

$1$ ) and (

$2$ ).

From (

$1$ ), LHS RHS.

From (

$2$ ), LHS RHS.

Since LHS RHS in both the equations, then

$(5,-1)$ is .

2. Solve the system of linear equations

$x + 3y = 16$ and

$2x - y = 4$ by substitution method.

Answer:

$x =$

$y =$
