(2, 5)

Step-by-step explanation:

Given the systems of equation

y = 4x - 3

y = -2x+9

Since both are y values, we will equate the right hand side of the equations

4x -3 = -2x+9

Collect the like terms

4x+2x = 9+3

6x = 12

x = 12/6

x = 2

Substitute x = 2 into any of the equation.

Using equation1;

y = 4x - 3

y = 4(2) - 3

y = 8 - 3

y = 5

Hence the solution to the system of equation is (2, 5)

Regular selling price (price before discount) 100%.

Price after trade discount of 15% is 85% of regular selling price..

Price after trade discount reduced to 10% is 90% of regular selling price.

By reducing the trade discount from 15% to 10% meant increasing the selling price by 5% of the selling price before applying the trade discount.
