Answer:
20x = 55
Step-by-step explanation:
First you have to add 3x to both sides of 11-3x=x
Now that you have 11 = 4x you divide 4 on both sides
11/4 = x
But you can't divide 11 by 4 unless you are looking for the decimal form of 11/4 which is 2.75
so now we take 11/4 or 2.75 depending on if you need your answer in fraction or as a decimal and replace that with x however both will equal the number 55
The first step for solving this expression is to distribute 
through the first set of parenthesis.
× (x - 9)
Now use the FOIL method to multiply each term in the first parenthesis by each term in the second parenthesis. This will look like the following:
x × x - x × 9 - x - × (-9)
Remember that multiplying two negatives together equals a positive,, so the expression changes to:
x × x - x × 9 - x + × 9
Calculate the product of all of the sets of multiplication to make the expression become:
x² - 
x - x +
Lastly,, calculate the difference of -x - x to find your final answer.
x² - 
x +
