Answer

$x=3$

Work Step by Step

Given the equation: $5(2x - 3) = 15$ We start by opening up the brackets as shown below: $10x - 15 = 15$ Next, we isolate the variable $x$ by adding $15$ to both sides of the equation as shown below: $10x - 15 + 15 = 15 + 15$ Simplifying, we have: $10x = 30$ We now divide through by the coefficient of the variable $x$ as shown below: $\frac{10}{10}x = \frac{30}{10}$ Simplify to get: $x = 3$ Therefore, the equation has a possible solution at the point $x = 3$
