Final answer:
To find the value of k that makes the equation 2k+3=48 true, subtract 3 from both sides of the equation and divide both sides by 2.
Step-by-step explanation:
To find the value of k that makes the equation 2k+3=48 true, we need to isolate the variable k.
Subtracting 3 from both sides of the equation, we have 2k = 45.
Then, dividing both sides of the equation by 2, we get k = 22.5.
