Question

How do you solve `20x+25=175`?

Answer 1

The answer is `x=7.5`

Explanation:

When solving equations, you need to take away parentheses and addition/subtraction first. Since there are no parentheses, do add/sub. You subtract 25 from both sides, and you get `20x=150` Next, you single out the variable, by dividing both sides by 20. 150/20 is 7.5, thus `x=7.5`

Answer 2

`x=7.5`

Explanation:

Solve:

`20x+25=175`

Subtract `25` from both sides.

`20x+25color(red)(-25)=175color(red)(-25`

Simplify.

`20x+0=150`

`20x=150`

Divide both sides by `20`.

`(cancel20x)/cancelcolor(red)20=150/20`

Simplify.

`x=7.5`
