<u>Step 1: Define equation</u>
2.5x + 10 = x - 0.5
<u>Step 2: Solve for </u><em><u>x</u></em>
Subtract <em>x </em>on both sides: 1.5x + 10 = -0.5 Subtract 10 on both sides: 1.5x = -10.5 Divide both sides by 1.5: x = -7
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
Substitute: 2.5(-7) + 10 = -7 - 0.5 Multiply: -17.5 + 10 = -7 - 0.5 Add/Subtract: -7.5 = -7.5
