What is the sum of (–2.1x + 3.7) and (5 + 4.9x)?

It's easier to work with problems such as –2.1x + 3.7 -5 + 4.9x when we rearrange the like terms vertically:

–2.1x + 3.7 -5 + 4.9x

becomes

–2.1x + 3.7

+4.9x -5

2.8x - 1.3 (answer)

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15
