108 - 76 = 32
so your answer is, it's worth $32
Solution
For this case we can do the following:
11y - 3x = 18
16y -3x = 33
We can multiply the first equation by -1 and we got:
-11y +3x =-18
16y -3x = 33
_______________
16y -11y = 33-18
5y = 15
y= 15/5 = 3
And then solving for x we got
x = -(18 -11*3)/ 3= -15/3 = 5
Answer: The greatest common factor is 6.
Step-by-step explanation:
18 goes into 6, 3 times
30 goes into 6, 5 times and q2 goes into 6, 2 times
Divide all three numbers by 6.
The new equation will look like: 3x-5+2y
