Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define equation</u>
3x - 17 = 2x + 35
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 2x on both sides: x - 17 = 35
- Add 17 to both sides: x = 52
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 3(52) - 17 = 2(52) + 35
- Multiply: 156 - 17 = 104 + 35
- Subtract/Add: 139 = 139
18 is 75! this is the answer to 18
