135 + y x 9,5 + y : 0,125 = 310
135 + y x 9,5 +y x 8 = 310
135 + y x (9,5 + 8) = 310
135 + y x 17,5 = 310 - 135
y x 17,5 = 175
y = 175 : 17,5
y = 10

135 + y x 9 , 5 + y : 0 , 125 = 310
135 + y x 9 , 5 + y x 8 = 310
y x ( 9 , 5 + 8 ) = 310 - 135
y x 17 , 5 = 175
y = 175 : 17 , 5
y = 10
Vậy y = 10
Tham khảo nha !!!
Làm
135 + y x 9 , 5 + y : 0 , 125 = 310
135 + y x 9 , 5 + y x 8 = 310
y x ( 9 , 5 + 8 ) = 310 - 135
y x 17 , 5 = 175
y = 175 : 17 , 5
y = 10
Vậy y = 10

Ta có:\(135+y\times9,5+y:0,125=310\)
\(\Rightarrow y\times9,5+y\times8=310-135\)
\(\Rightarrow y\times\left(9,5+8\right)=175\)
\(\Rightarrow y\times17,5=175\)
\(\Rightarrow y=175:17,5\)
\(\Rightarrow y=10\)
<=> y*(9,5+1/0,125)=310-135
<=> y*(9,5+8)=175
<=> y*17,5=175 => y=175:17,5=10
Đáp số: y=10

135 + y x 95 + y x 8 = 310
y x 103 = 175
y = 175/103
