Answer:
add 3 to both sides of the equal sign
Step-by-step explanation:
to solve the equation you would have to add three
that is because you have to do inverse operations
and you would add because the opposite of subtracting is adding
so solving it would look like this
x - 3 = 12
+3 +3
x = 15
this is how you check the answer:
15 - 3 = 12
about 11.50
6 / 5.70 = 1.05
1.05 x 11
hope this helps
Answer would be
V= - uf/f-u
See notes

B.
there cannot be two of the same x value's. It would make it a circle on the graph, or something close to that, which isn't a function.
