RideAnS [48]

Answer:

-x^{2}+4x

Step-by-step explanation:

we have

(x^{2}+x)-(2x^{2} -3x)

step 1

Eliminate the parenthesis

x^{2}+x-2x^{2} +3x

The symbol of the term 3x is incorrect, must be positive instead of negative

so

-(-3x)=+3x

Group terms that contain the same variable

(x^{2}-2x^{2})+(x+3x)

Combine like terms

-x^{2}+4x

By selling a watch in Rs 150 and Rs 200 loss and profit are happened
Travka [436]

Answer:

Rs 175

Step-by-step explanation:

Suppose the cost is x and at Rs150 the loss is 150-x (this should be a negative number).

At Rs200, the profit is 200-x.

So we have an equation: minus 150 minus x is equal to 200 minus x.

To solve the equation, the cost price X is Rs175.
