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.
To solve the expression 6(x 5), first clarify the multiplication. If "x" represents multiplication, the expression translates to 6 multiplied by 5, which equals 30. If "x" is a variable, then the expression simplifies to 30x. Thus, the final answer depends on whether "x" is treated as a variable or a multiplication symbol.
12 + 5 equals...
5 + 4g - 7 is an expression, not an equation (or inequality). An expression cannot be solved.
In the expression (5 + 3b), the coefficient is the number that multiplies the variable (b). Here, the coefficient is (3). The term with the variable is (3b), while (5) is a constant term and does not have a coefficient associated with a variable.
The question contains an algebraic expression but there is no equation to solve.
The algebraic expression for 5 times a plus 6 times a squared can be written as (5a + 6a^2). In this expression, (5a) represents 5 times the variable (a), and (6a^2) represents 6 times the variable (a) squared.
To replace a variable with a number, simply identify the variable in your equation or expression and substitute it with the desired numerical value. For example, if you have the expression ( x + 5 ) and you want to replace ( x ) with 3, you would write it as ( 3 + 5 ). This substitution allows you to evaluate the expression or solve an equation more easily.
The coefficient is the number in front of the variable a, or 5.
If you mean -6+4x-5 then the given expression can be simplified to 4x-11 and the unknown variable is x
