Five more than twice a number is -13 find the number
Let's call the unknown number x. We want for what number(s) is x + 2x > x -1 true. x + 2x > x -1 Combine like terms: 3x > x - 1 Subtract x from each side: 2x > -1 Divide each side by 2: x > -1/2 Any number greater than -1/2 will work.
Howe much is eight more four?
2n + 2 = 2(n + 1)Since you have been given that it is twice a variable with the variable only, you have 2n, and adding 2 yields 2n + 2, or 2(n + 1).
2x+3 where x is the unknown number
-424Four times the unknown number
yes
3
Four more than twice a number.
If the unknown number is q then: 2q+25 = 72
Four more than twice a number.
2x + 4 < x x < -4
It is an algebraic expression in the form of 2x+6 whereas x is the unknown variable
The question can be represented as the equation, 2n + 5 = 4n + 3 where n is the unknown number. 2n + 5 = 4n + 3 : subtract 2n from both sides 5 = 2n + 3 : subtract 3 from both sides 2 = 2n : divide both sides by 2 1 = n The unknown number has been identified as 1.
Call your number some variable, for example, "n". Twice the number would be 2n, adding four to that you get 2n + 4, and six times all that is 6(2n + 4), which is the same as 12n + 24.
2 x = 8 + 4x
