User: Simplify the expression below. –(–7y + 12)

Weegy: first distribute, multiplication of the same signs is always positive (like (-)(-) and (+)(+)) and multiplication of the opposite is (like (-)(+) or vice versa). [ so : ?(?7y + 12) you have this: (?1)(?7y + 12) which is " (?1)(?7y ) + (-1)(+12) (-)(-) = + and (-)(+) = - 7y - 12. ]

User: Solve the equation. Show your work. 45 = 3b + 69

Weegy: b is equal to 8. You will get this by: 45 = 3b+69 3b = 69-45 3b = 24 (divide both side by 3) b = 8

8x – 12 = 4x + 24

8x - 4x = 24 + 12

4x = 36

x = 9
