This is a basic algebraic equation
And will be using PEMDAS to solve
P: Parentheses
E: exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction
If you are unaware of PEMDAS this is the order at which you solve algebraic equation. So start from “P” and end with “S”
X= 2/3
2/3^3 Times 3 Divided by 2/9 + 9(2/3) - 7 - 6(2/3)
Now, personal I’d choose to convert fractions to decimals to simplify solving the equation. I doubt this is the only way to solve for the equation but I find this is the easiest
To convert a fraction to decimal you divide the numerator by the denominator.
So 2/3 is 0.666667
And
That means 2/9 is 0.222222
0.666667^3*3/0.222222+9(0.666667)-7-6(0.666667)
Making you answer roughly -0.999989
Hope this helps, but I’m not sure if this is completely right or not
