The price, e, of an entertainment system at extreme electronics is $220 less than twice the price, u, of the same system at ultra electronics. the difference in price between the system at extreme electronics and ultra electronics is $175. which system of linear equations can be used to determine the price of the system at each store?

The system of linear equations that can be used to determine the price of the system at each store will be

e = 2u - 220  and  e - u = 175

LINEAR EQUATION

The general formula of a linear equation is

Y = mx + c

Where

Given that The price, e, of an entertainment system at Extreme Electronics is $220 less than twice the price, u, of the same system at Ultra Electronics. That is,

e = 2u - 220 (1)

The difference in price between the system at Extreme Electronics and Ultra Electronics is $175. That is,

e - u = 175 (2)

Solve equation 1 and 2 simultaneously by substituting e in equation 1 into equation 2

2u - 220 - u = 175

u - 220 = 175

u = 175 + 220

u = 395

Substitute u into equation 1 or 2 to get e

e = 2(395) - 220

e = 790 - 220

e = 570

The system of linear equations that can be used to determine the price of the system at each store will be

e = 2u - 220  and  e - u = 175

let

e=the price of an entertainment system at Extreme Electronics

u=the price of an entertainment system at Ultra Electronics

We know that

e=2*u-220> equation 1

e-u=175> equation 2

substitute equation 1 in equation 2

{2*u-220}-u=175> u=175+220>u=$395

e=2*395-220>e=$570

therefore

the answer is

the system of linear equations is

e=2*u-220> equation 1

e-u=175> equation 2

e=$570

u=$395
