Answer:
You should start with a simple equation. And remember- practice makes perfect.
The basic algebraic equation involves simple addition or subtraction with one unknown quantity, such as 2 + x = 7.
1. Subtract 2 from both sides: 2 - 2 + x = 7 - 2.
2. Simplify the equation by doing the math: 2-2+x=7-2=0+x=5, or x = 5.
3. Check your work by substituting the answer, 5, into the equation for x.
The correct answer is x=5.
Hey! Not to good at explaining this, but the correct answer is 3/5 hours, or 36 minutes.
