Question

21+4x=61 .............................

Answer 1

Answer: x = 10

Explanation:

We have the equation 21 + 4x = 61

The first thing we do is subtract 21 from both sides.

21 + 4x = 61

4x = 40

Now, we can solve the equation by dividing both sides by 4.

4x = 40

x = 10

Answer 2

x = 10

Explanation:

given the equation

21 + 4x = 61 ( subtract 21 from both sides )

21 - 21 + 4x = 61 - 21 ( simplify both sides

4x = 40 ( divide both sides by 4 )

`(4)/(4)` x =
`(40)/(4)` , that is

x = 10
