Divide by 5 on both sides to get:
x=19/5

Answer 2

x = 3
`(4)/(5)`

Explanation:

5x+1=20

To solve the equation above, we will follow the steps below;

Subtract 1 from both-side of the equation

5x + 1 - 1 = 20 -1

5x = 19

Divide both-side of the equation by 5

`(5x)/(5)` =
`(19)/(5)`

(On the left-hand side of the equation, 5 at the numerator will cancel-out 5 at the denominator leaving us with just x, while on the right-hand side of the equation 19 will be divided by 5)

x =
`(19)/(5)`

x = 3
`(4)/(5)`
