The steps below show the incomplete solution to find the value of x for the equation
7x − 3x − 4 = −1 + 21:

step 1: 7x − 3x − 4 = −1 + 21
step 2: 7x − 3x − 4 = 20
step 3: 4x − 4 = 20

which of these is most likely the next step?

4x = 24
4x = 16
4x = 5
4x = 80

4x = 24

Step-by-step explanation:

Step 1: 7x − 3x − 4 = −1 + 21

Step 2: 7x − 3x − 4 = 20

Step 3: 4x − 4 = 20

ADD 4 + 20 because we are doing inverse operations

Step 4: 4x =24

Have a great day!

BTW it was right on the FLVS test:)

part a

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
