Question

Which equation would best help solve this problem?
Five added to 2 times a number is equal to 7 less than 4 times the number.
a. 2x + 5 = 4x – 7
b. 4x +7 = 2x – 5
c. 5x + 2 = 7x – 4
d. 2x – 5 = 4x + 7

Answer 1

If the word number is replaced by x, and the words 'added', 'times', 'equal' and 'less than' are replaced by symbols, you would be left with: 

5 + 2x = -7 + 4x

If you slightly reorder is, you get:
2x + 5 = 4x - 7

The answer is a.
