The answer would be 2400 square feet 60*40 = 2400

You need a picture of the table :(

2x + 4 = 2x + 2

2x - 2x = 2 - 4

0 = -2 ......(when the variables drop out and ur left with an untrue statement, this means there are no solutions)

2x + 5 = 2x + 5

2x - 2x = 5 - 5

0 = 0.....(when the variables drop out and ur left with a true statement, this means there is infinite solutions)

so the two possible solutions when the variables drop out are : no solutions and infinite solutions
