What’s a proof for 3x=6

There's nothing to prove here, this is an equation, and you may solve it.

In order to do so, you must recall that you're allowed to divide both sides of any equation by any non-zero number, and the solution(s) won't change.

In this case, if you divide both sides by 3, you'll get

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
