Answer:
x=7 and y= 1/3
Step-by-step explanation:
we have -5x - 15 = -30 <=> x + 3 = 10
x= 7
if x=7
so 2×7 - 6y = 12 <=> 14 - 12 = 6×y
2 = 6y
y= 2/6 = 1/3
Hey there!!
Given:
... A=3B+7C
Subtracting 7C on both sides:
... A-7C=3B
Dividing by B on both sides:
... (A-7C)/3=B

Let x be a variable.
Using the ratio and the given number of 117, we can create the following formula:
1x + 3x + 9x = 117, where 3x is the cups of onion
Simplify this equation.
13x = 117
Divide both sides by 13
x = 9
We want to solve for 3x, so multiply both sides by 3
3x = 27
As I started earlier, 3x is how many cups of onions is needed; thus, 27 is our answer. Hope this helps! :)
