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.

2x = 76 x = 38
The algebraic expression for "twice a number" would be 2x, where x represents the unknown number. To find the quotient of 2x and 6, you would divide 2x by 6, which simplifies to (2x) / 6. This can be further simplified to x / 3, which represents the final quotient of twice a number and 6 in algebraic expression.
2x + w = -w

n + 2n = 3n
If: x+18 = 2x Then: x = 18

6+2x=18 x=6
It would be: 2x+4 = 19

It could be: 2x+16 = -24 in which case the value of x is -20
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
