Answer: x = 5

Explanation:

First, let’s get rid of the number without the x, 5.

In order to do that, we need to solve for the inverse. Inverse means opposite.

The inverse (opposite) of adding 5 is subtracting 5. So, we subtract 5 from the 5 and the 20.
20 - 5 = 15

Before:
3x + 5 = 20

After:
3x = 15

Now, what’s the inverse to 3x? 3x signifies multiplying 3 and an unknown number. So, the opposite of that would be dividing 3.

Divide 3 on both sides, the 3x and the 15.
15/3 = 5

Before: 3x = 15

After: x = 5

Therefore, your final answer is x = 5

Answer:

x = 5

Explanation:

To solve for x in the equation 3x + 5 = 20, follow these steps:

Subtract 5 from both sides to isolate the term with 3x on the left side:

3x + 5 - 5 = 20 - 5

This simplifies to:

3x = 15

Now, to solve for x, divide both sides by 3:

3x / 3 = 15 / 3

x = 5

So, the solution to the equation 3x + 5 = 20 is x = 5.
