How many inches is in a book case

The standard height for a two-shelf bookcase is 32 inches. The standard width is 31 inches. The depth will range from 12 to 13 inches. However, it's not hard to find a two-shelf bookcase as tall as 36 inches

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
