<h3>What is a proportion?</h3>
A proportion is a <u>fraction of total amount.</u> Then, to find how much greater an amount a is compared to an amount b, the expression is
.

If 21 is added to (+ 21) a number (x) the result (=) is 40 less than (- 40) twice the number (2x)
x + 21 = 2x - 40 Add 40 to both sides
x + 61 = 2x Subtract x from both sides
61 = x Switch the sides to make it easier to read
x = 61
Answer:
x is 5
