First, you put 93 over 100.
Then, you simplify the fraction. But it is in simplified form.
Answer is 93/100.
You take the x and change it to the other side to leave y by itself and then divide by 2 = Y=-3-x

Hope this will help
The answer would be multiplication and subtraction
Answer:
tall candles = 39
Short candles = 52
Step-by-step explanation:
let tall candles be x
and short candles be y
No. Of candles sold = x + y =91
Money made from candles will be equal to = 8x + 5y = $572
These both are simultaneous linear equations.
x + y =91 ( multiply by 5)
5x + 5y = 455
8x + 5y = $572
Subtract them:
-3x = -117
x = -117/3
x = 39
put value of x in
x + y = 91
39 + y = 91
y = 91 - 39
y = 52
x shows tall candles so they are 39
y shows short candles so they are 52
