-13x(2/3)-0.34x(2/7)x(-13)-(5/7)x0.34
= -13x(2/3)-0.34x[(2/7)x(-13)+(5/7)]
= -13x(2/3)-0.34x[2x(-13)+5]/7
= -13x(2/3)-0.34x3
= -(13x2+0.34x3x3)/3
= -2906/300
= -1453/150
= -13x(2/3)-0.34x[(2/7)x(-13)+(5/7)]
= -13x(2/3)-0.34x[2x(-13)+5]/7
= -13x(2/3)-0.34x3
= -(13x2+0.34x3x3)/3
= -2906/300
= -1453/150
