20 points- these are the four questions i'm stuck on for my review assignment and i would appreciate if you showed your steps in how you got the answer.

#1. 6 - 4(3 + x) = 6

#2. 62x + (3) (4) = 74

#3. 13 (x + 6) - 3 = 3x -5

#4. -x + 42 = -4x

Use the x-intercept method to find all real solutions of the equation. -9x^3-7x^2-96x+36=3x^3+x^2-3x+8

1foot = 12 inches; 1 yard = 3 feet
