Subtract \( 2x \) from both sides: \( x - 7 < 5 \).
["SEO Article: How to Solve Inequalities: Subtracting ( 2x ) from Both Sides of ( x - 7 < 5 )", "Understanding how to manipulate inequalities is a critical skill in algebra. One common operation is subtracting the same term from both sides, which helps isolate the variable and simplify the expression. In this article, we’ll explore how subtracting ( 2x ) from both sides of the inequality ( x - 7 < 5 ) leads to a clearer, solvable form — and why proper technique matters.", "---", "### Why Subtracting ( 2x ) from Both Sides Matters", "When solving inequalities, the goal is to isolate the variable ( x ) on one side. Subtracting ( 2x ) from both sides maintains the balance of the inequality while simplifying your work. This technique is fundamental because it keeps the inequality’s truth intact while transforming the expression into a more manageable form.", "---", "### Step-by-Step: Subtracting ( 2x ) from Both Sides of ( x - 7 < 5 )", "Start with the original inequality:\n[\nx - 7 < 5\n]\nTo simplify and isolate ( x ), subtract ( 2x ) from both sides:", "[\nx - 7 - 2x < 5 - 2x\n]", "Now simplify both sides:", "[\n(x - 2x) - 7 < 5 - 2x\n]\n[\n- x - 7 < 5 - 2x\n]", "The inequality now reads:\n[\n- x - 7 < 5 - 2x\n]", "This step may seem counterintuitive because we introduced ( -x ) and the negative sign, but it’s essential for maintaining logical equivalence. The inequality remains true as long as both sides are manipulated consistently.", "---", "### Moving Forward: Solving the Updated Inequality", "Although subtracting ( 2x ) simplified the expression, solving for ( x ) requires careful next steps. To eliminate the negative sign before ( x ), add ( 7 ) to both sides:", "[\n- x - 7 + 7 < 5 - 2x + 7\n]\n[\n- x < 12 - 2x\n]", "Now add ( 2x ) to both sides to bring all ( x )-terms to one side:", "[\n- x + 2x < 12\n]\n[\nx < 12\n]", "---", "### Final Answer & Key Takeaway", "So, the solution to ( x - 7 < 5 ), after subtracting ( 2x ) from both sides and simplifying step by step, is:\n[\n\boxed{x < 12}\n]", "Key takeaway: When solving inequalities, subtracting the same term (including negative coefficients like ( 2x )) from both sides preserves the inequality’s truth.
