Solving the Linear Equation: 3x + 2(10 − x) = 24
Solving the Linear Equation: 3x + 2(10 − x) = 24
Understanding how to solve linear equations is a fundamental skill in algebra—essential not only for academics but also for real-world problem-solving. In this comprehensive guide, we will walk step-by-step through the solution of the equation:
3x + 2(10 − x) = 24
The Original Equation
Start with the equation:
3x + 2(10 − x) = 24
Understanding the Context
Step 1: Expand the Parentheses
The first step is to eliminate the parentheses. Multiply 2 across the terms inside:
3x + 2 × 10 − 2 × x = 24
Which simplifies to:
3x + 20 − 2x = 24
Step 2: Combine Like Terms
Combine the x-terms on the left side:
(3x − 2x) + 20 = 24
This gives:
x + 20 = 24
Step 3: Isolate the Variable
Subtract 20 from both sides to solve for x:
x + 20 − 20 = 24 − 20
Therefore:
x = 4
Final Answer
The solution to the equation 3x + 2(10 − x) = 24 is:
x = 4
