Question

Your thinking of a number,such that, if you subtract 3 from the product of that number and 7, and then divide that difference by 13, and then double that quotient and add 30, you'll end up with 50. what number are you thinking of?

Answer 1

2[(7a - 3) / 13] = 50

Answer 2

i still dont understand

Answer 3

a is your number

7a is the product of a and 7

7a -3 is subtracting 3 from the product of a and 7

(7a-3) / 13 is dividing the difference from the product of 7 subtracted by 3

2[(7a-3) / 13] is doubling the quotient.

2[(7a-3) / 13] = 50 is making it equal 50

Answer 4

yes but is it "a" or do i have to find the value of "a"

Answer 5

find a, no kidding.
