That's more than 12 decimal places but it's all I remember off-by-heart.
Mr. Arnold needs to paint 1,600 square feet of his house. Each gallon of paint will cover 250 square feet. So you would divide 1600 by 250 to figure out how many cans he needs. the answer is 6.4. Then it says that he had one left over from the last time he painted his house. So he only needs 5.4 gallons now. The end question is whether or not Mr. Arnold needs more than 5 gallons and the answer is yes. Because he needs 5.4 gallons. .4 gallons more than 5.
First, you must distribute the negative sign(otherwise considered a negative one). This gives you x - 4x + 7 = 5x - x - 21.
Then, simplify any like terms you can: -3x + 7 = 4x - 21.
Simplify this even further: 28 = 7x
The final answer is x = 4
