2x + 7
It is 2n + 20.
If: x+18 = 2x Then: x = 18
It would be: 2x+4 = 19
It is not an equation but an algebraic expression that can be simplified to: 12b-5a
2x + 7
It is 2n + 20.
n + 2n = 3n
If: x+18 = 2x Then: x = 18
x2+7
It would be: 2x+4 = 19
The algebraic equation for half a number plus 7 can be represented as (1/2)x + 7, where x represents the unknown number. In this equation, the term (1/2)x denotes half of the number, and adding 7 accounts for the additional value. This equation can be used to calculate the result when half of a number is added to 7.
