Final answer:
The solution to the equation 13 = 15 - 4x is x = 1/2. This was found by rearranging and simplifying the equation step by step.
Step-by-step explanation:
To solve for x in the equation 13 = 15 - 4x, you can start by simplifying and rearranging the terms. Here's a step-by-step process:
Begin with the original equation: 13 = 15 - 4x
Subtract 15 from both sides of the equation: 13 - 15 = -4x
Simplify the left side: -2 = -4x
Divide both sides by -4 to isolate x: x = -2 / -4
Simplify the right side: x = 1/2
So, x equals 1/2.
