Leni [432]

Answer:

Step-by-step explanation:

price of tv and sales tax = 1.0688×$189 = $202.0032 ≅ $202.00

4 years = 3×365 days + 366 days = 1461 days

cost of electricity = 1461 days × $0.06/day = $87.66

lifetime cost = purchase price + electricity + repairs

= $202.00 + $87.66 + 2·$29

How do you do it ???
ss7ja [257]
4x+y=25
x-3y=16

substitute the value of y into the equation by moving 4x (from the first equation) to the right side
y=25-4x

substitute the given value of y into the equation x-3y=16

x-3(25-4x)=16
x-75+12x=16 (add 75 to both sides of the equation)
13x=91 (divide by 13 both sides of the equation)
x=7

y=25-4x=25-(4×7)=25-28=-3

answer: x=7, y=-3
