Solve 4x - 3 = 18. Round to the nearest thousandth.
lorasvet [3.4K]

Answer:

x=5.250

Step-by-step explanation:

We have been given an equation 4x-3=18. We are asked to solve our given equation.

First of all, we will add 3 to both sides of our equation.

4x-3+3=18+3

4x=21

Now, we will divide both sides of our equation by 4.

\frac{4x}{4}=\frac{21}{4}

x=5.25

Upon rounding our answer to nearest thousandth (3 places after decimal) we will get,

x=5.250

Therefore, the solution for our given equation is x=5.250.
