r = 25
r + 14 = 39 r = 25
This equation has no value, as the value of n could be anything, giving this equation an infinite number of answers. To answer this equation, you either need to know what n is, or have an equals sign.
y is the variable

3d + 14 = 11 is the equation.
2x + y = 25 x + y = 14 Subtract second equation from the first: x = 11 Substitute this value of x in the second equation: 11 + y = 14 ie y = 3

It is an equation and the value of n is 14
No unfortunately this is not an equation. An equation must end with an equals sign. 5b + 14 is simply two terms.
y is the variable
25
10 which gives s a value of 24
