Question

Peter is given the following equation. What operation should he use to solve for W?

Answer 1

The correct answer is Option 1: multiplication

Explanation:

Given equation is:

`20 = (w)/(6)`

Given equation is a linear equation with one variable w. In order to solve the linear equations in one variable, properties of equality are used.

Solving for w means that w has to be isolated on one side of the equation i.e. w should be without a multiple or denominator.

The equation will be multiplied by 6 to remove the denominator in w/6

`20*6 = (w)/(6) *6\\w = 120`

Hence,

The correct answer is Option 1: multiplication
