The answer is D) Yes; because x and y must be integers, and integers are rational.
Answer:
b = (d-c)/a
Step-by-step explanation:
ab + c = d
We want to solve for b, so we need to get b alone
Subtract c from each side
ab+c-c = d-c
ab = (d-c)
Divide each side by a
ab/a = (d-c)/a
b = (d-c)/a
Here’s a pic of my work, it shows that the numbers 2,7,0 repeat.
