Question

How do I solve 5a + 17 = 47

Answer 1

Hi there!

There are two steps to take when solving this equation, but before we even think about that, let's start by rewriting the equation.

5a + 17 = 47

Step 1) Subtract 17 from both sides.

5a + 17 - 17 = 47 - 17

5a = 30

Step 2) Divide both sides by 5.

5a/5 = 30/5

a = 6

So, your final answer therefore is

a = 6

Hope this helps!

TIP - This method can be used when solving any equation with 1 variable. :D
