The product of a number and 20
The difference is ten times the number.
15n
Represent the number by n. The equation is 5n - 1 = 3n +5, and the solution is n = 3.
The product of five and the sum of a number and six can be expressed mathematically as ( 5 \times (x + 6) ), where ( x ) represents the number. This means you first add the number ( x ) to six and then multiply the result by five.

Let's represent the number as (x). The phrase "Eight less than five times a number" can be translated to (5x - 8), and "is seven more than the number" can be translated to (x + 7). Therefore, the algebraic equation representing the given phrase is (5x - 8 = x + 7).
5-2x=7This can be solved.Subtract five from each side: -2x=2Divide each side by negative 2: x=-1That is your final answer. If you plug -1 into the equation, it will work.
Represent the number by n. The equation is 5n - 1 = 3n +5, and the solution is n = 3.
