2x-3=x+2 answer x=5
Let the number be x and so: 2x+3 = 15 with the value of x being 6
3*(n - 5) = 2*n + 11
Then the number is 3

2x+3 where x is the unknown number
18
The algebraic expression for three more than a number is: X + 3
Three more than twice a number.
2x+3=11
It is: 3x = 2x+8 and the value of x is 8
Five more than twice a number is -13 find the number
2x-3=x+2 answer x=5
Let the number be x and so: 2x+3 = 15 with the value of x being 6
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).
3*(n - 5) = 2*n + 11
