Question

0.75h + 3 = 12 What's the answer?

Answer 1

Answer:

h = 12

Step-by-step explanation:

Given

0.75h + 3 = 12 ( subtract 3 from both sides )

0.75h = 9 ( isolate h by dividing both sides by 0.75 )

h = 12

Step-by-step explanation:

Step 1: Define equation

0.75h + 3 = 12

Step 2: Solve for h

1. Subtract 3 on both sides:                    0.75h = 9
2. Divide 0.75 on both sides:                  h = 12

Step 3: Check

Plug in h into the original equation to verify it's a solution.

1. Substitute in h:                    0.75(12) + 3 = 12
2. Multiply:                               9 + 3 = 12
3. Add:                                     12 = 12

Here we see that 12 does indeed equal 12.

∴ h = 12 is a solution of the equation.
