If x is your variable, it would be 6x+7x. If x is negative, it would be 6(-x)+7(-x).
7 x n
48-n=4n-7
7x4+8
In order to write seven and two tenths, a person should simply use the period between the two numbers as the "and." To write the number in numerical form, the number would appear as 7.2.
To express "seven increased by a number," you can use the variable ( x ) to represent the unknown number. The mathematical expression would be written as ( 7 + x ). This indicates that you are adding the number ( x ) to seven.
7x +9 = 6x
7 x n
48-n=4n-7
7x4+8
X = number 48 - X = 4X - 7
The real answer is n-7
