Answer:
we're just multiplying X × 2 every time so (y=80)
X is positive 2 and y is positive 1
A) x=2; i’m guessing if you meant by 4x+1=x+7
Isolate the variable, and see what kind of equation it is. if it's adding, let's say, then add one number to itself. this cancels it out, so it's taken care of. next, add that same number to the second one, and take the result. you should be able to subtract that from the answer i believe, it's been a while since I've done these so it might not be spot on
