The expression "twice the difference of x and 5" would look like this: 2(x-5). To solve the problem, you would first subtract 5 from x, and then multiply the difference by two.
The expression is: 5(b + x)
-2
5
Multiply the entire expression by a least common multiple and then simplify the expression. In this case, the least common multiple is 30 so multiply the entire expression by 30 and simplify.

2*5 + 3
It means to replace a mathematical expression by a simpler one. For example, if x = 2 times 5 + 3, you can multiply 2 times 5 to obtain x = 10 + 3. Doing the addition will simplify the expression even further.It means to replace a mathematical expression by a simpler one.

A verbal expression for 5 a-b is that it is 5 is multiplied by the difference between a and b.
They are values, they are constants and in the context of the multiply sign being an operator, then they are operands.

It is easier to describe using an actual example. Say you have an expression x/sqrt(2). Then multiply by sqrt(2)/sqrt(2) (which is of course equal to 1 and we know that anything multiplied by 1 stays the same. This will get rid of the radical on the bottom. So the expression becomes x/sqrt(2) * sqrt(2)/sqrt(2) = [x*sqrt(2)]/2 where * means multiply
