Suppose you spent $74.95 for a shirt and a jacket. The shirt cost $20.25. Solve the equation 20.25+j=74.95 to find how much you spent on the jacket.
You can work a simpler problem to estimate an answer. Use number sense to solve 20+j=75

They've given you the formula. You just need to solve for \(j\).

If I told you 4 plus a number equals 9, how would you figure out what "the number" is? Tell me your process.

when burned, 18 gallons of gasoline produce about 360 pounds of carbon dioxide. solve the equation 18n=360 to find how much carbon dioxide 1 gallon of gasoline produces.

360 = 18x if you divide by 18 you would get 20 because if 10 x 18 = 180 then 20 x 18 would be double that and 180 x 2 = 360
