Henry predicted that he would pick a red color card of the time in his color card experiment. Henry picked a card, recorded the color then put the card back into the bag before
picking the next. He picked cards at random 30 times. If Henry's prediction is true, how many
times will he pick a red color card out of the bag?

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

2

=

10

x=5
