It could be: 2x+16 = -24 in which case the value of x is -20
2x + w = -w
If: x+18 = 2x Then: x = 18
6+2x=18 x=6
It would be: 2x+4 = 19
5
2x + w = -w
n + 2n = 3n
40
If: x+18 = 2x Then: x = 18
3a-6x2
6+2x=18 x=6
It would be: 2x+4 = 19

The algebraic expression "twice a number z" can be represented as 2z. In this expression, the variable z represents the unknown number, and multiplying it by 2 gives you twice that number. This expression can be used in algebraic equations and formulas to represent scenarios where a number needs to be doubled.
