The desired value will be the solution to the equation ...

... (5 - a) = 20 + (6a - 1)

... 5 - a = 19 + 6a . . . collect terms

... 5 = 19 + 7a . . . . . . add a

... -14 = 7a . . . . . . . . . subtract 19

... -2 = a . . . . . . . . . . . divide by the coefficient of x

The value of the variable is -2.

A projector was sold after allowing 10% discount on the marked price and levying 13% VAT .If the selling price of the projector
Tom [10]

The marked price of the projector is $50,000.

<h3>What is the marked price?</h3>

The price of the projector after the discount can be represented with:

(100 - 10%)x - 90%x = 0.90x

Where x is the marked price

The price of the projector after the VAT is : (1.13) x 0.90x = 1.02x

Difference in price = 1.02x - 0.90x = 5850

0.12x = 5850

x = 5850 / 0.12

x = $50,000
