Question

a. 1/2[3/2(x+5)+2/3(x+6)]=x+4
. x-2/3+2=x-2/5+6

Answer 1

A. 1/2[3/2(x+5)+2/3(x+6)]=x+4
1/2 [ 3/2x + 15/2 + 2/3x + 4 ] = x + 4
1/2 [ 13/6x + 23/2] = x + 4
13/12x + 23/4 = x + 4
13/12x - x = 4 - 23/4
1/12x = -7/4
x = -7/4  / 1/12
x = -21

B. x-2/3+2=x-2/5+6
    5 (x -2) + 2 = 3 (x -2) + 6
    5x - 10 + 2 = 3x - 6 + 6
          5x - 3x = -6 + 6 + 10 - 2
                 2x = 8
                   x = 8 /2
                   x = 4
