Q
Q: Find the value of x in the equation 5x - 2(3 - x) = 4.
Solution:
Distributing gives 5x - 6 + 2x = 4. Combining like terms: 7x - 6 = 4. Thus, 7x = 10, x = 10/7.
Steps: 7
Show Steps
Step 1: Start with the equation: 5x - 2(3 - x) = 4.
Step 2: Distribute the -2 to both terms inside the parentheses: 5x - 2 * 3 + 2 * x = 4.
Step 3: Calculate -2 * 3, which is -6, and rewrite the equation: 5x - 6 + 2x = 4.
Step 4: Combine like terms (5x and 2x): (5x + 2x) - 6 = 4, which simplifies to 7x - 6 = 4.
Step 5: Add 6 to both sides of the equation to isolate the term with x: 7x - 6 + 6 = 4 + 6.
Step 6: This simplifies to 7x = 10.
Step 7: Divide both sides by 7 to solve for x: x = 10 / 7.
