To solve the expression 18 times 3x plus 12 times 2x for the value of x, we first simplify the expression using the distributive property:
18(3x) + 12(2x) = 54x + 24x
Next, we can combine like terms:
54x + 24x = 78x
Now, we set the expression equal to a given value, if there is one. If there is no given value, we can leave the expression as is.
Since there is no given value, we leave the expression as:
78x
Therefore, the value of x is not defined by the expression alone.
