Question

How many solutions does 5x=30 have

Answer 1

One solution

Explanation:

We are given the following equation and we are to determine the number of solutions this equation has:

`5 x = 3 0`

For that, we will solve it.

Dividing both the sides by 5 to get:

`\frac { 5 x } { 5 } = \frac { 3 0 } { 5 }`

`x = 6`

Therefore, this equation has only one solution.

Answer 2

For this case we must find the solutions of the following equation;

`5x = 30`

We clear the value of the variable "x", dividing by 5 on both sides of the equation:

`x = \frac {30} {5}`

`x = 6`

Answer:

`x = 6`

We have a single solution of a linear equation.
