Neville is making a 180-piece jigsaw puzzle that is 4 times as many pieces as luna's.
luna has already used 15 pieces of her puzzle. if n is the number of puzzle pieces that
luna has left, how many pieces is n? explain how you calculated your answer.

n = 30 pieces

Step-by-step explanation:

Firstly calculate the number of pieces that Luna's puzzle has,

;180 ÷ 4 = 45 pieces

Hence if Luna has used 15 pieces...then the number of pieces left,

; 45 - 15 = n

;Hence..., n = 30 pieces

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
