Hi Daniellepowers!

To solve this system of equations, add the two equations.
2x+3y=40
+
-2x+2y=20

5y=60
y=12

Plug y back into any equation,
2x+3(12)=40
2x+36=40
2x=4
x=2

Solution: (2, 4)

B. <span>x= 2 y=12

How to find cp if loss and sp are given

velikii [3]

Step-by-step explanation:

$\tt{ \: H \: E \: Y \: \: T \: H \: E \: R\: E \: }$ !

When Loss and Selling price ( SP ) are given , Cost price ( CP ) can be found out using the following formulae :

✰ $\large{ \boxed{ \boxed{ \tt{CP = Loss + SP}}}}$

$\text{How \: did\: we \:get \:the \: formula : \: CP \: = Loss \: + \: SP} \:$ ?

We simply derived the formula from Loss = CP - SP.

First , Swap the sides of the equation :

⟶ $\text{CP - SP = Loss}$

Move SP to right hand side and change it's sign :

⟶ $\text{CP = Loss + SP}$

This is how , CP can be obtained when we are given loss and SP.

Hope I helped ! ♡
