\(y.2+y.3=1985\)
\(< =>y\left(2+3\right)=1985\)
\(< =>5y=1985\)
\(< =>y=\frac{1985}{5}=397\)
Y *2 +Y*3=1985
Y*(2+3)=1985
Y*5=1985
Y=1985 chia cho 5
y=397
y.2+y.3=1985
y(2+3)=1985
y.5=1985
y=1985 : 5
y=397
Bài làm:
\(y\times2+y\times3=1985\)
\(y\times\left(2+3\right)=1985\)
\(y\times5=1985\)
\(y=1985\div5\)
\(y=397\)
Học tốt!!!!
Y x 2 + Y x 3 = 1985
=> Y(2 + 3) = 1985
=>Y x 5 = 1985
Y = 1985 : 5
Y = 397
y x 2 + y x 3 = 1985
y ( 2 + 3 ) = 1985 =>>> 5y = 1985 =>>> y = 397
Vậy : y = 397
y x 2 + y x 3 = 1985
y x ( 2 + 3 ) = 1985
y x 5 = 1985
y = 1985 : 5
y = 397
các bạn học tốt nhé !
\(y\times2+y\times3=\)\(1985\)
\(y\times\left(2+3\right)=1985\)
\(y\times5=1985\)
\(y=397\)
Vậy \(y=397\)
y x 2 + y x 3 = 1985
y x ( 2 + 3 ) = 1985
y x 5 = 1985
y = 1985 : 5
y = 397
