Need a two step equation for number 3

so the bike costs $129, but she already has $24 saved, then she'll be saving $3 per week so let's take a peek at a table of those savings

week 1..................... total amount......... 24 + 3(1)

week 2..................... total amount......... 24 + 3(2)

week 3..................... total amount......... 24 + 3(3)

week 4..................... total amount......... 24 + 3(4)

week 5..................... total amount......... 24 + 3(5)

week w..................... total amount......... 24 + 3(w)

24 + 3x = 129

35 weeks

Step-by-step explanation:

She already has 24 dollars saved, but will save 3 dollars every week. Use x to represent the number of weeks. In total she will save 129.

Solve for x using the equation:

24-24 + 3x = 129-24

3x = 105

3x/3 = 105/3

x= 35

24+x=y

step-by-step explanation:
