Question

Please help! 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. Thanks!

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

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

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

#4. -x + 42 = -4x

Answer 1

Explanation:

(a)6-4 (x+3)=6

6-4x-12=6

-6-4x=6

-4x-6=6

-4x-6+6=6+6

-4x=12

-4/4=12/-4

x=-3
