Step-by-step explanation:

5x+3y = 12 ...1

4x-5y = 17 ...2

...1 × 5 both sides of the equation

25x + 15y = 60 ...3

...2 × 3 both sides of the equation

12x - 15y = 51 ...4

...3 + ...4

25x + 15y + 12x -15y = 60+51

Evaluate 81/4-615/32
Kaylis [27]

Answer:33/32

Step-by-step explanation:

81/4 - 615/32

32•4=128 to get a common denominator

Then whatever you do to the top you do to the bottom.

81•32=2,592

Then you would do

615•4=2,460

Now you have

2,592/128 - 2,460/128

Now you subtract

2,592-2460=132

You keep the denominator

132/128 and then simplify by dividing both numbers by four and you get

33/32
