Question

\(x\) x 2,5 -3,46 = 4,68

\(x\): 1,2 + 2,15 = 7,28

Answer 1

help me !!!!!!

Answer 2

x*2,5-3,46=4,68

<=> x*2,5=8,14

<=>x=3,256

Vậy x=3,256

x:1,2+2,15=7,28

<=>x:1,2=5,13

<=>x=6,156

Vậy x=6,156

Answer 3

\(X.2,5-3,46=4,68\)

\(\Leftrightarrow X.2,5=4,68+3,56=8,14\)

\(\Leftrightarrow X=8,14:,25=3,256\)

\(VayX=3,256\)

\(X:1,2+2,15=7,28\)

\(\Leftrightarrow X:1,2=7,28-2,15=5,13\)

\(\Leftrightarrow X=5,13:1,2=6,156\)

\(VayX=6,156\)

Answer 4

X x 2,5 -3,46=4,68

X x

Answer 5

\(x\times2,5-3,46=4,68\)

\(x\times2,5=4,68+3,46\)

\(x\times2,5=8,14\)

             \(x=8,14:2,5\)

             \(x=3,256\)

\(x:1,2+2,15=7,28\)

\(x:1,2=7,28-2,15\)

\(x:1,2=5,13\)

         \(x=5,13\times1,2\)

         \(x=6,156\)
