It helps you because it makes it easier to divide you just have to keep using place value to find the quitent
3(x)-10=x+4. That’s the equation. Ight, now we gotta solve it. It would be 3x-10=x+4, then you subtract 4 from each side, so 3x-14=x, then subtract 3x, so -2x=-14, then divide -2x by -2 and -14 by 2, which means the answer is x=-7. Thank me later.
I don’t know how to necessarily complete the tables but i know they are equivalent
1. 3(x-5)
3 (x) = 3x
3 (-5) = -15
that is the distributive property thus it equals
3x - 15
2. 3x - 15
they’re the same
The answer is f=3. You get this by combining like terms.
