Answer 1

Answer:

ididnt think so

Step-by-step explanation:

2×5 are you know that is so easy

Answer 2

$\sf \red{Let \: us \: assume }$

$\sf{two \: numbers \: be : \: x \: and \: y}$

$\sf \red{Given}$

$\sf{sum \: of \: two \: number \: is \: 2 \implies \: x + y = 2} - - - (1)$

$\sf{their \: difference \: is \: 5 \implies \: x - y = 5} - - - (2)$

$\sf \red{By \: soving \: (i) \& (ii) \: we \: get :}$

$\sf{x + y = 2} \\ \sf{x - y = 5} \\ - - - - - \\ \sf{2x = 7 } \\ - - - - -$

$\boxed{\boxed{ \sf{x = \frac{7}{2} }}}$

$\sf \red{substituting \: x = \frac{7}{2} \: in \: eq.(1)}$

$\sf{ \frac{7}{2} + y = 2}$

$\sf{ \frac{7 + 2y}{2} = 2 }$

$\sf{7 + 2y = 2 \times 2}$

$\sf{7 + 2y = 4}$

$\sf{2y= 4 - 7}$

$\sf{2y = - 3}$

$\boxed{ \boxed{ \sf{y = \frac{ - 3}{2} }}}$

$\boxed{ \boxed{ \sf \red{the \: numbers \: are : \: \frac{7}{2} \: \& \: \frac{ - 3}{2} }}}$
