The sum of 14 and twice a number y is equal to 78 ?

14 + 2y = 78

32 To solve this problem, we need to set up an equation based on the information given. Let's break it down step by step.

Step 1: Assign a variable to the unknown number. Let's call it "y".

Step 2: Translate the given information into an equation. The sum of 14 and twice a number y is equal to 78. Mathematically, this can be represented as:

14 + 2y = 78

Step 3: Solve the equation for y.

Subtract 14 from both sides of the equation to isolate 2y:

2y = 78 - 14
2y = 64

Finally, divide both sides of the equation by 2 to solve for y:

y = 64 / 2
y = 32

So, the answer is y = 32.
