Answer 1

a,

5xX+6/7=11/12

5 x X=11/12-6/7

5 x X=5/84

X=5/84:5

X=1/84

B,

X :6/5-11/3=3/5

X:6/5= 3/5+11/3

X:6/5=64/15

X=64/15x6/5

X=126/25

NHỚ ****!!!!!!!!!!

Answer 2

a) 5*x+6/7=11/12

5*x=11/12-6/7=77/84-72/84

5x=5/84

x=5/84:5

x=1/84

b) x:6/5-11/3=3/5

x:6/5=3/5+11/3=9/15+55/15

x:6/5=64/15

x=64/15*6/5

x=128/25

Chúc bạn học tốt!^_^
