Subtract 5 from each side of the model

Answer 1

The first step will be subtract 3 from each side of the model.

Step-by-step explanation:

By subtracting 3 from each side of the model, the 3 in the Right Hand Side will be cancelled, and the model will be:

2x = 5 - 3 = 2

Then the next step will be dividing 2 from each side of the model.

Solution:

2x + 3 = 5

By subtracting 3 to both the sides, we get

2x + 3 - 3 = 5 - 3

or, 2x = 2

By dividing 2 to both the sides, we get

2x/2 = 2/2

or, x = 1

Answer:

The value of x is 1.
