An expression cannot be solved; an equation or an inequality may be.
In the expression 5 + y + 8, y is a variable. We know how much 5 and 8 are, those are definite quantities. Only y has an unknown, and hence variable value.
-3
There is no equation, only an expression. An expression can be simplified but cannot be solved.
12 + 5 equals...
5 + 4g - 7 is an expression, not an equation (or inequality). An expression cannot be solved.
The question contains an algebraic expression but there is no equation to solve.
The coefficient is the number in front of the variable a, or 5.
12
If you mean -6+4x-5 then the given expression can be simplified to 4x-11 and the unknown variable is x
The question should be what is the variable in the following expression? (n + 5) The answer: (n) represents the variable. See: Variable(English definition) then look up the Math/Algebra definition.
You cannot solve it though it is possible to evaluate the expression. -5 + 9 * 6 = -5 + 54 = 49
