What is 9-9/9+9-9/9
/ means divide

16 i think

Step-by-step explanation:

Order of operations is PEMDAS (parenthesis, exponents, multiply/divide left to right, add/subtract left to right). So with multiplication/division or addition/subtraction, you do whichever operation comes first left to right.

9+9–9x9/9 means 9x9 first and then divide that by 9.

So this becomes 9+9–81/9

which becomes 9+9–9

So add/subtract left to right to get 18–9

which gives you answer of 9.

Step-by-step explanation:

65

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
