Addition undoes subtraction;multiplication undoes division.x + 7 = 12 → x = 12 − 7x + 7 = 12x = 5Subtract 7 from both sides.x − 4 = 9x = 13Add 4 to both sides.3x = 21x = 7Divide both sides by 3.x / 5 = 4x = 20Multiply both sides by 5.THE COMMON MISTAKE✗ 3x = 21 → x = 21 − 3✓ 3x = 21 → x = 21 ÷ 33x means 3 times x, so the inverse is dividing, not subtracting.Always substitute your answer back into the original.
