Okay:





#1. (7 + 5*3) / (3*1/6) = (7 + 15) / (3/6) = 22 / (1/2)


If you hate working with fractions you can convert the (1/2) to 0.5 which will give you: 22 / (0.5). You should be able to solve this from here, just divide.





#2. (42.18) / (4.89 + 2.68) = (42.18) / (7.57). You should be able to just divide from here.





#3. I think you want to solve for x in this problem? I am not quite sure what you're asking me to do, but I'll solve for x (in case): 4(2x - 3) = 6 - (3 - 2x)


First, multiply through: 8x - 12 = 6 - 3 + 2x (keep all your -/+ signs in order!)





Then, get like terms on the same side of the equation: 8x - 2x = 6 - 3 +12





Now add/subtract the like terms: 6x = 15





Now divide by 6 on both sides of the equation to solve for x. You should be able to do this part yourself.





#4 3 + (5 + 7) = (5 + 7) + 3 is associative property. This is also true when you multiply--notice when you change the groupings the answer is still the same.





#5 5 = 0 + 5 is additive property. This is true when adding, but not changing the "outcome"--ie 0 + x = x.





#6 (7-4)^4 - (5*x) (I THINK THIS IS WHAT YOU'RE SAYING THE EQUATION IS? I HOPE...)


First, subtract what is in the parentheses (7-4) = 3 so now you know you have (3)^4 and you should know that (3)^4 is 81





So you now have 81 - 5x. These two terms are different. 81 is a constant while the other has an x as a variable. You cannot further simplify this problem.
