Question

Check whether the solution, x=3, is correct by using substitution.
Now, let’s focus on the right side. Evaluate the expression on the right side of the equation.
5(x+2)
=
2x+19

5(3+2)
=
?

2(3)+19

5(5)
=
?

2(3)+19

25
=
?

Answer 1

Let's substitute \( x = 3 \) into both sides of the equation and evaluate.

**Left Side:**

The left side of the equation is:

\[ 5(x + 2) \]

Substituting \( x = 3 \):

\[ 5(3 + 2) = 5(5) = 25 \]

**Right Side:**

The right side of the equation is:

\[ 2x + 19 \]

Substituting \( x = 3 \):

\[ 2(3) + 19 = 6 + 19 = 25 \]

Now we compare both sides:

- Left Side = 25
- Right Side = 25

Since both sides are equal, the solution \( x = 3 \) is indeed correct.
