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
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
Number one = x Number two = y Number three = z x + y + z = 26The second number is twice the first. y = 2x The third number is 6 more than the second. z = y + 6 z = 2x + 6 x + 2x + (2x + 6) = 26 5x = 20 x = 4 Number one = 4 Number two = 8 Number three = 14
