First, you have to know exactly what you're looking for. It doesn't help to

vaguely know only that you need to "work it out". You have to know that

you're looking for the definite value for 'w' that makes the equation a true

statement. Here's how to find it:

5 (4 + w) = 10

Eliminate parentheses on the left side:

20 + 5w = 10

Subtract 20 from each side:

5w = -10

Divide each side by 5:

w = -2

That's the number that 'w' must be. If 'w' is not -2, then

5(4 + w) is not equal to 10.
