What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Let the number be x.
I am thinking of a number. I multiplied this number by 3, subtracted 8, and doubled the result, then added 14.
First part:
2(3x - 8) + 14
6x - 16 + 14
6x - 2
Then I added 50% of what I had and then added 11.
Second part:
(6x - 2) + 50/100 (6x - 2) + 11
6x - 2 + 3x - 1 + 11
9x + 8
Then I divided by 5. After all that, I was left with 8.
Third part:
(9x + 8) / 5 = 8
9x + 8 = 40
Subtract 8 on both sides.
9x = 40 - 8
9x = 32
Divide both sides by 9.
x = 32/9
Thus,
The number that was started with is 32/9.
