Algebra solutions Step-by-Step Method
1. Understand the question
● Identify what you need to find (the unknown), usually represented by a letter like x, y, or
z.
● Example: 2x+3=72x + 3 = 72x+3=7
Here, we need to find the value of x.
2. Simplify both sides
● Combine like terms and simplify expressions if needed.
○ Example: 3x+2x=5x3x + 2x = 5x3x+2x=5x
3. Move variables to one side and numbers to the other
● Use addition/subtraction to isolate the variable.
○ 2x+3=72x + 3 = 72x+3=7
○ Subtract 3 from both sides → 2x=42x = 42x=4
4. Solve for the variable
● Divide or multiply to get the variable alone.
○ 2x=42x = 42x=4
○ Divide both sides by 2 → x=2x = 2x=2
Answer: x = 2
5. Check your answer
Plug the value back into the original equation:
● 2(2)+3=72(2) + 3 = 72(2)+3=7
● 4+3=74 + 3 = 74+3=7 Correct! text here
