5 / 3 · [ 1/2 · ( x + 4/3 ) - 7/5] = - 3/2
 [ 1/2 · ( x + 4/3 ) - 7/5] = - 3/2 x 3/5 
1/2 * (x+4/3 ) - 7/5 = - 9/10 
1/2 * (x +4/3) = -9/10 + 7/5 
1/2 *( x+4/3) = 1/2
x + 4/3 = 1/2 : 1/2 
x + 4/3 = 1 
x = 1- 4/3 
x = - 1/3

X÷2+2÷3-7÷5=-3÷5*3÷5
X÷2+2÷3-7÷5=-9÷10
X÷2+(10-21)÷15=-9÷10
x÷2-11÷15=-9÷10
x=-1÷3
