You have to get x on its own.
5x=49-4
5x=45
45 divided by 5
Therefore x=9

Okay -

So, the goal when we have an equation is to find the value of the variable. So, let's isolate that variable on one side of the equation!

* original equation 
5x + 4 = 49.

* subtract four from both sides. if you do something on one side of the equation, you have to do it on the other.
5x + 4 - 4 = 49 - 4.

* now we are going to divide 5 on both sides to isolate x.
5x/5 = 45/5.

* and our answer is...
x = 9. =)

Jason puts $30 worth of gas in his truck. The price per gallon was $2.50. Which equation can be solved to find the number of gal

tankabanditka [31]

So, this is a rate problem, so the forumla we would get is

2.5g=30

(Note this is not one of the choices), so if we look, there is an equivelent equation.

If we divide both sides by g we get

2.5=30/g

B is the correct answer
