Question

Solve the given equation with the given property

Answer 1

1.)

5/4+(-6/7-8/5)=(5/4-6/7)-8/5

5/4+(-30-56)/35=(35-24)28-8/5

5/4-86/35=11/28-8/5

(175-344)/140 = (55-224)/140

-169/140=-169/140

2.)

5/4-(-6/7+8/5)=(5/4+6/7)+8/5

5/4-(-30+56)/35=(35+24)/28+8/5

5/4-26/35=59/28+8/5

(175-104)/140=(295+224)/140

71/140=! 518/140
