Question

tìm x, biết:

60 - ( 15 x X + 4 ) = 15/2 : 1/2

CÁC BẠN GIÚP MÌNH VỚI MÌNH GẤP LẮM NHA!

CẢM ƠN CÁC BẠN.

Answer 1

60-[15*X+4]=15/2:1/2

60-[15*X+4]=15

15*X+4=60-15

15*X+4=45

15*X=45-4

15*X=41

X=41:15

X=41/15

Answer 2

ko ghi đề

\(60-\left(15.x+4\right)=\frac{15}{2}.\frac{2}{1}\)

\(60-\left(15.x+4\right)=15\)

\(15.x+4=60-15\)

\(15.x+4=45\)

\(15.x=45-4\)

\(15.x=41\)

\(x=41:15\)

\(x=\text{2.7333}\)

Answer 3

à nhầm bạn ơi 

\(41:15=\frac{41}{15}=2\frac{11}{15}\)

Answer 4

\(60-\left(15\times x+4\right)=\frac{15}{2}:\frac{1}{2}\)

\(60-\left(15\times x+4\right)=\frac{15}{2}\times\frac{2}{1}\)

\(60-\left(15\times x+4\right)=15\)

\(15\times x+4=60-15\)

\(15\times x+4=45\)

\(15\times x=45-4\)

\(15\times x=41\)

\(x=41:15\)

\(x=\frac{41}{15}\)
