Question

clear fractions or decimals , solve and check
3.7x + 45.5 = 4.7 - 6.5x

Answer 1

What do you mean when you say "clear fractions or decimals"

Answer 2

3.7x + 45.5 = 4.7 - 6.5x
+6.5x +6.5x
10.2x+45.5=4.7
-45.5 -45.5
10.2x=-40.8
divide all by 10.2
and you get x=-4

Answer 3

If you want to check your work then plug your "Y" back in like
3.7(-4)+ 45.5 = 4.7 - 6.5(-4)
30.7=30.7 so you are right!
@ChmE I'm pretty sure that just means make sure that you do not have any fractions or decimals left. That's why it says "clear".
