Study Notes

Equations and Expansions

To solve for x in the equation 2x + 5 = 17, subtract 5 from both sides, resulting in 2x = 12, then divide both sides by 2 to get x = 6.
To solve for y in the equation 3y - 7 = 20, add 7 to both sides, resulting in 3y = 27, then divide both sides by 3 to get y = 9.
The correct expansion of (x + 3)(x - 4) is x^2 - x - 12.
