Want this question answered?
an expression
the value of the exponent n1
The expression appears to be: (12-4t)/6
It is an expression with a single variable, x.
The best algebraic expression for 7 x plus 12 -4 is 7x+8.
That will depend on the plus or minus value of 12 which has not been given.
It is 6a + 12, an expression which cannot be evaluated without the value of a.
Negative 12 minus 3 plus 9 is equal to -6
An expression cannot be solved: only an equation or inequality has solutions.
