Question

How do you solve `w+19=49`?

Answer 1

For this you will have to do basic algebra, and isolate the variable.

Explanation:

To isolate the variable, you will have to get it alone on one side of the equation. In order to do this, you will have to take away the numbers that is on the same side as the variable in the equation.

Since it is a positive 19 that is being added to the "w" variable, you will have to subtract 19 to get "w" by itself. However, be careful because whatever you do to one side you must do to the other. Because of this rule, you will have to subtract 19 from the 49 as well. This means that the right side of the equation will equal 30, and the left side will equal to "w", meaning the value of "w" is 30.

`w + 19 = 49`
`w + (19 - 19) = (49 - 19)`
`w + 0 = (49-19)`
`w = 30`

Answer 2

`w=30`

Explanation:

`w+19=49`

`w=49-19`

`w=30`
