Answer:

22/15=x

Step-by-step explanation:

Well first off we have to do the stuff in the parentheses-

3x(3+7)-42=2

9x+21x-42=2              Now we have to get x by itself

          +42  +42

9x+21x=44                Now add the like terms

30x=44                   Divide by 30

/30  /30                    30 chancels out

44/30                Simplify

22/15=x

Do the parenthesis first, 3+7=10, then do the exponent and get 256,multiply 3 times 10 and get 30, do 256 divided by 2 and get 128, finally do 30-128 to get 98.

98 is your answer
