Need asap! if you do this page for me i’ll love you forever. and eternal love is worth doing a few math questions right? leah bought 4 pens and a bottle of nail color. her sister bought 2 of the same pens and 4 bottles of nail color, and spent the same amount as leah. the nail color cost $2. use algebra tiles to find the cost of each pen.

see explanation

Step-by-step explanation:

Step 1

4x + 2 = 2x + 8 ← model of the situation

Step 2

Subtract 2x from both sides of the equation

4x - 2x + 2 = 2x - 2x + 8 ← simplify

2x + 2 = 8

Step 3

Subtract 2 from each side

2x + 2 - 2 = 8 - 2 ← simplify

2x = 6

Step 4

divide both sides by 2

x = 3

As a check

Substitute x = 3 into both sides of the equation and check validity

left side : (4 × 3) + 2 = 12 + 2 = 14

right side : (2 × 3) + 8 = 6 + 8 = 14

Both sides of the equation = 14, hence

Cost of each pen is $3

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

i can you with this question sweetie!
