solve df + 10h=3 for h

10 h = 3 - d*f

Next, divide both sides of the equation by 10.

Then you will have the answer.

(x+3y=6)(-2)

2x-7y=-1

To solve the equation "df + 10h = 3" for h, we need to isolate the variable h on one side of the equation. Here's how we can do it step by step:

Step 1: Start with the original equation: df + 10h = 3.

Step 2: To isolate h, we need to get rid of df on the left side of the equation. We can do this by subtracting df from both sides of the equation:
df + 10h - df = 3 - df, which simplifies to:
10h = 3 - df.

Step 3: Now we have 10h = 3 - df. To isolate h, we need to get rid of the coefficient 10. We can do this by dividing both sides of the equation by 10:
(10h)/10 = (3 - df)/10, which simplifies to:
h = (3 - df)/10.

Therefore, the solution to the equation "df + 10h = 3" for h is:
h = (3 - df)/10.
