What is the SI Unit for Energy?
The SI Unit for Energy is Joule. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton metre or N⋅m).
Solve for x: 40 = 10 + 2x
To solve for x, you must first remember that x needs to equal the number you are solving for. For this to happen you must use addition, subtraction, multiplication, or division depending on the equation. In this instance, first you must subtract 10 from 10 which becomes zero and subtract 10 from 40 which becomes 30. Finally, you must divide 2x by 2 which leaves you with x. Also, you must divide 30 by 2 which leaves you with 15. This leaves us with x = 15 our answer.
