Ok, so let’s solve for x. Let’s start with the original equation. 18-5x=48 We can subtract 18 from both sides to start the process of isolating x. -5x=30 now, divide each side by -5 to isolate x, thus solving the equation for x. x=-6 Solving for an unknown variable is all about taking it one step at a time to isolate the variable to one side. :)
