Answer:
X=5.7
Step-by-step explanation:
5x-3-2x/7=24
We simplify the equation to the form, which is simple to understand
5x-3-2x/7=24
Simplifying:
5x-3-0.285714285714x=24
We move all terms containing x to the left and all other terms to the right.
+5x-0.285714285714x=+24+3
We simplify left and right side of the equation.
+4.71428571429x=+27
We divide both sides of the equation by 4.71428571429 to get x.
x=5.72727272727

81 servings. I found this by making a ratio:
24 c 108 c
------- = -------
18 ser x
I then cross multiplied to get the equation: 24x=1,944. I solved this equation to find x, the number of servings in 108 cups, which was 81.
I remember doing this back in elementary school. I had a hard time with it too!
