Answer:
x = 2/5
Step-by-step explanation:
5x=2
Divide each side by 5
5x/5 = 2/5
x = 2/5
Answer:
x=9
Step-by-step explanation:
hope this helps i think it's right 60=9x - 21 you add 21 to both sides and get 81 = 9x then divide 81 by 9 and get x=9
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 +
