You said that (15 - 3x) = 21 . Divide each side of the equation by 3: (5 - x) = 7 Add 'x' to each side: 5 = 7 + x Subtract 7 from each side: -2 = x
The number is 26
When 3 times a number is decreased by 4 the result is 17. what is the number?
three times a number decreased by eleven
if the quotient of -20 and 4 is decreased by 3
6n - 3n which simplifies to 3n.

Answer = 7 - 3n
three times a number decreased by eleven
if the quotient of -20 and 4 is decreased by 3
6n - 3n which simplifies to 3n.
Thirty decreased by three times a number is six less than three times the number. Find the number.
Three Working backwards from 11 then add 4 to make 15 then dividing 15 by 5 makes 3
The equation can be expressed as: ( 9 - 3x = 5(y + 5) ), where ( x ) is the unknown number being decreased and ( y ) is the unknown number being summed with five. This states that nine decreased by three times ( x ) is equal to five times the sum of ( y ) and five.
Nine times a number decreased by four can be expressed mathematically as ( 9x - 4 ), where ( x ) represents the unknown number. This expression indicates that you first multiply the number by nine and then subtract four from the result.
How do you write half a number decreased by 8 is equal to the sum of the number and 14
