PEMDAS: parenthesis, exponents, multiply, divide, add, subtract
Lets' work on the parethesis first.
100-9^2
We can do the exponent first, 9^2=81, so 100-81=19
Then we divide and 19/3 is your final answer.

Answer:
x = -1
Step-by-step explanation:
2x - 7 = 9x
Subtract 2x from both sides: -7 = 7x
Divide both sides by 7: -1 = x
Now plug in 7 for every value of x in the original equation to make sure you are correct:
2(-1) - 7 = 9(-1)
-2 - 7 = -9
-9 = -9
I hope this helps!
