All number in percentage form when converted into a fraction will serve as the numerator with 100 as the denominator. The percent sign will be removed and the fraction will be simplified.

42% = 42/100 = (42÷2) / (100÷2) = 21/50 
72% = 72/100 = (72÷2) / (100÷2) = 36/50 = (36÷2) / (50÷2) = 18/25
88% = 88/100 = (88÷2) / (100÷2) = 44/50 = (44÷2) / (50÷2) = 22/25
35% = 35/100 = (35÷5) / (100÷5) = 7/20

Notice that both numerator and denominator must be factored by the same number to be simplified.

Put each one over 100. So 42/100, then reduce down by dividing by 2 both the top and bottom figures and you get 21/50 for your first answer. Do the same with each of the rest...72/100 and reduce down to 36/50, then reduce again 18/25 and that is the farthest you can reduce on that one. Do the same for the rest.

What is the solution? pls help
loris [4]

Answer:

Solve by substitution

[y=5/2x-4]

[y= -x+3]

Substitute y = -x +3

[-x+3=5/2x-4]

Isolate x for -x+3=5/2x-4: x=2

For y = -x+3

Substitute x = 2

y= -2+3

Simplify

y=1

The solutions to the system of equations are:

y=1 x=2
