16/15 x 48 - 48 x X = 20
51,2 - 48 x X = 20
48 x X = 51,2 - 20
48 x X = 31,2
X = 31,2 : 48
X = 0,65
(16/15-x)48=20
16/15-x=20:48
16/15-x=5/12
x=16/15-5/12
x=64/60-25/60=39/60=12/20=3/5=0.6
0,65 nhé mình chắc chắn 100% luôn cá nữa
ta có :48x(16/15-X)=20
=>16/15-X=20:48
=>16/15-X=5/12
=>X=16/15-5/12
=>X=13/20
48 * (16/15 -x ) = 20
16/15 -x = 20 :48
16/15 -x = 5/12
x = 16/15 - 5/12
x = 13/20
13/20 nhe ban

48.(\(\frac{16}{15}\)-x)=20
\(\frac{16}{15}\)-x=20:48
\(\frac{16}{15}\)-x=\(\frac{20}{48}\)
\(\frac{16}{15}\)-x=\(\frac{5}{12}\)
x=\(\frac{16}{15}\)-\(\frac{5}{12}\)
x=\(\frac{64}{60}\)-\(\frac{25}{60}\)
x=\(\frac{39}{60}\)
x=\(\frac{13}{20}\)
khiếp lên online math để hỏi trong nâng cao thôi mình ko nói với ai đâu đừng lo ok
