Correct answer: A
Step-by-Step Solution
To solve the linear equation 5x - 17 = -x + 7, follow these steps to isolate the variable x:
Group the variable terms: Add x to both sides of the equation to bring all x terms to one side. 5x + x - 17 = 7 6x - 17 = 7
Group the constant terms: Add 17 to both sides of the equation to isolate the term with x. 6x = 7 + 17 6x = 24
Solve for x: Divide both sides by 6.
x = 24 / 6
x = 4
