Final answer:
To solve for x in the equation 5(3x + 4) = 23, distribute the 5, subtract 20 from both sides, and then divide by 15 to find that x equals 0.2.
Step-by-step explanation:
To find the value of x in the equation 5(3x + 4) = 23, you need to use basic algebraic techniques. First, you distribute the 5 into the parentheses: 5 * 3x + 5 * 4 = 23, which simplifies to 15x + 20 = 23. Next, you subtract 20 from both sides to get 15x = 3. Finally, you divide both sides by 15 to solve for x, resulting in x = 3/15 which simplifies to x = 0.2.
