Solve for 𝑥 x in the equation: 3 𝑥 − 5 = 16

Question

To solve the equation 3x−5=16, follow these steps:

1. Add 5 to both sides to isolate the term with x:

3x−5+5=16+5

3x=21

Simplifying:

1. Divide both sides by 3 to solve for x:

x=7

Answer 1

This question was answered correctly. If we plug x=7 back into the original equation, we can see that 3(7)-5 = 21-5 = 16, which matches the right side.

Answer 2

3x−5=16

Note: The goal is to solve for x by isolating x on one side.

1) Add 5 on both sides to get: 3x = 21.

2) Divide both sides by 3 to get: x = 7.

3) Therefore, our solution is x = 7.

Answer 3

Question:

Solve for x in the equation: 3x - 5 = 16

To solve the equation 3x -5 = 16, we used the systematic approach. Here's how to do it step-by-step, noting the vital points along the way.

Step 1: Isolate the variable terms.

First, we want to get all terms involving x on one side of the equation and constant (numbers) terms on the other side.

Step 2: Use Addition method to start solving the equation

We add 5 to both sides of the equation to eliminate the -5

3x -5 + 5 = 16 + 5 Use Basic Arithmetic to simplify the equation

3x= 16 + 5

3x = 21

Step 3: Use the Division method to solve for x

3x = 21

Divide both sides of the equation by 3 to solve for x

3x divided by 3 = 21 divided by 3

x = 21 divided by 3

x = 7

Solution:

The answer to the equation 3x - 5 = 16 is x = 7
