Answer:

thre is nothing there

Step-by-step explanation:

Answer 2

For a Pair of Linear Equations to have Infinite Solutions, Then,

$\frac{ a_{1} }{ a_{2} } = \frac{b_{1}}{b_{2}} = \frac{ c_{1} }{ c_{2} }$

We know,

$a_{1}$ = 1

$a_{2}$ = $a - b$

$b_{1}$ = 2

$b_{2}$ = $a + b$

$c_{1}$ = -1

$c_{2}$ = $-a - b + 2$

Hence, Putting the Values,

$\frac{1}{a - b} = \frac{2}{a + b} = \frac{ - 1}{ - a - b + 2}$

Solving the Equations,

$a = 3b$

Putting this value in 2nd and 3rd Equation,

We get $b = 1$ and $a = 3$

Hope it Helps
