Solve the equation 5x+3=38

Excellent question! We need to isolate x on to one side of the equation.

Let's see then: x is being multiplied by 5, then having 3 added to it. Let's do the inverse of this then. Let's subtract 3 from both sides of the equation, which gives us:

5x = 35

Now we can divide both sides by 5:

x = 35/5

Meaning that x = 7.

Plug in our value for x into the original equation to make sure you have the right answer:

5 x 7 + 3 = 38?

35 + 3 = 38?

38 = 38

Use the properties of equality. Therefore, x is equal to 7
