|-2|=2x+3
<=> 2x+3=|-2|
=>2x+3=2
=>2x=2-3
=>2x=-1
=>x=\(\frac{-1}{2}\)
/ -2 / = 2x + 3
\(=>2=2x+3\)
\(=>-1=2x\)
\(=>-2x=1\)
\(=>x=\frac{-1}{2}\)
Ủng hộ mik nha
2x + 3 = |-2|
2x + 3 = 2
2x = 2 + 3
2x = 5
x = 5/2
ủng hộ mk nha!!!
2x+3=|-2|=2
=>2x=2-3=-1=>x=(-1):2
\(=>x=-\frac{1}{2}\)
Vậy.........
/-2/=2x+3
=> 2=2x+3
=> 2-3=2x
=>-1=2x
=> -1/2=x
Vậy x=-1/2
