1. solve the equation and check your solution: 3(x+6)=18+3x 2. solve the equation and check your solution: -2(x-1)=2-2x
3. Solve the equation and check your solution: x + 4 = - 2 + x
4. solve the equation and check your solution: -2(x+2)=5 - 2x

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

d

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

-1   1/6.   you dont subtract the denominators
