Steps for finding the solution

We have 5x + 4 = 0

First, we move the non x terms to the RHS of the equation. To do this, we subtract 4 from both sides.

Note: if a = b, then a - c = b - c

Therefore, 5x + 4 - 4 = 0 - 4

or, 5x = -4

Next, divide both sides by 5, which is the coefficent of x

Note: if a = b, then a ÷ c = b ÷ c

5x/5 = -4/5

x = -4/5 or, x = -0.8

Solve another equation

𝒙 + =

𝒙 + = 𝒙 +

Enter any three values:
