Question

Solve for x: 5x + 15 = 28

Answer 1

First do
5x = 28 - 15

Answer 2

5x + 15 = 28
- 15 -15
5x=13

5x/5=13/5

x=13/5 is the furthest you can simplify

Answer 3

Then do
x = answer / 5

Answer 4

\[5x + 15 = 28\]

Now we must subtract 15 from both sides because its '+15' so we have to work backwards and subtract

\[5x+15−15=28−15 \ so \ 5x=13 \]

Now, we have to divide, so we have to add fraction bars

As, you would know, a fraction bar is a division symbol so,

_5x__ = _13____
5 5

So \[x=blank\]
