Question

solve the equation


PLEASE PLEASE PLEASE PLEASE HELP ME

Answer 1

==================================
9) x - x/4 - 1/3 =2 + x/4
=> x - x/4 -x/4 = 2 + 1/3
=> (4x-x-x)/4 = (6+1)/3
=> 2x/4 = 7
=>x=14

12) -3(x+2) = 9
=>x+2 = 9/-3
=>x+2=-3
=>x = -3-2=-5
=>x = -5

15)(x-3)/2 - 4 = 9
=>(x-3)/2 = 9+4
=>(x-3)/2 = 13
=>x-3 = 13×2
=>x-3 = 26
=>x = 26+3
=>x = 29
