Question

check whether the solution, x = 3, is correct by using substitution. now, lets 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 = \square

Explanation:

Step1: Substitute $x=3$ into RHS

$2(3) + 19$

Step2: Calculate the product term

$6 + 19$

Step3: Sum the two values

$25$

Answer:

25
