58-2.x=63-x
=> -2x + x = 63 - 58
=> -x = 5
=> x = -5
vậy ...
-2x+x=63-58
-1x=5
=>1x=-5
x=-5
58-2x = 63-x
-x = 5
x = -5
vậy ...
\(58-2x=63-x\)
\(\Leftrightarrow-2x+x=63-58\)
\(\Leftrightarrow-x=5\)
\(\Leftrightarrow x=-5\)
Vậy :.....................
58 - 2.x = 63 - x
-2 . x + x = 63 - 58
-x = 5
\(\Leftrightarrow\)x = -5
Vậy x = -5
~ HOK TỐT ~
58 - 2x = 63 - x
<=> -2x + x = 63 - 58
<=> -x = 5
<=> x = -5
Vậy x = -5
