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
Answer:
22/15=x
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
