2x - 12y = B
(-5,-8)...x = -5 and y = -8
now we sub and solve for B
2(-5) - 12(-8) = B
-10 + 96 = B
86 = B <==
Subtract 27 from 36 = 9
9/36 = 0.25
To turn a decimal into a percent multiply by 100

Answer:
x=y-3
Step-by-step explanation:
okay, so first, we have to understand what the words mean.
PRODUCT: means the answer to a multiplication question
DECREASED: taken away or to make smaller
AND: addition or add
We can use X for "product" and Y for "a number"
now we can write it out:
x=y+5-3
OR
y+5-3=x
It isn't a real test. I do believe it helps you with your grade and the classes you'll take next year.
