Solving Algebraic Equations
-
To solve the equation 2X + 5 = 15, subtract 5 from both sides to obtain 2X = 10, then divide by 2, yielding X = 5.
-
In the equation X/3 - 7 = 5, first add 7 to both sides which results in X/3 = 12; multiplying both sides by 3 gives the solution X = 36.
-
The principle of maintaining balance in equations states that whatever you do to one side of the equation, you must do to the other side to keep the equation valid.
-
Inverse operations are fundamental in algebra; they are pairs of operations that reverse each other, such as:
- Addition is undone by subtraction
- Multiplication is undone by division
-
For the equation 5X + 7 = 42, begin by subtracting 7 from both sides resulting in 5X = 35; then, divide by 5 to find X = 7 as the solution.
