On these two number lines what do the shaded dots represent ? 20 points

A shaded dot on a number line indicates that the given number should be included as a possible solution, whereas an open dot indicates that the given number can't be a solution. For example, if you graph x > 7, you place an open dot at 7 because it's not a valid answer (7 is not greater than itself).

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x
