So this can be translated like the following:

Bike costs = 173 dollars She currently has 107. She saves 11 dollar per week to get the bike so the formula is:

173 = 107 + 11X where X is the number of weeks

Step 1: bring the 107 to the other side to get 173-107 = 11X

Step 2: divide both sides by 11 to solve for X to get this (173-107) / 11 = X

Step 3: Calculate and simplify 66 / 11 = X which is the same as X = 6

So the answer is it will take jennifier 6 weeks to save for the bike.
