What is 4k plus 1 equals 3.25?

Answer 1

Let's start by writing the problem.

4K + 1 = 3.25

Now we begin by removing the single term (1) from the left side. We must perform the opposite or inverse operation to remove it. In our case, the opposite or inverse of addition is subtraction.

4K + 1 - 1 = 3.25 - 1

We're left with the following problem: 4K = 2.25. Our next step is to disconnect the variable K from the 4. Remember in Algebra, we do the opposite or inverse operation and it needs to be done to both sides.

4K ÷ 4 = 2.25 ÷ 4

Lastly, we're left with our solution which is K = 0.5625

If we plug in our number we come to:

4(0.5625) + 1 = 3.25

2.25 + 1 = 3.25

3.25 = 3.25

So we'd rewrite the problem as: 4K + 1 = 3.25 when K = 0.5625.
