2x - 3 + 5 = 6
2x - 3 = 6 - 5
2x - 3 = 1
2x = 1 + 3
2x = 4
x = 4 : 2
x = 2
mk k rồi nha,k lại đi
2x - 3 + 5 = 6
2x + 2 = 6
2x = 6 - 2
2x = 4
x = 4 : 2
x = 2
2x - 3 + 5 = 6
2x = 6 - 5 + 3
2x = 4
x = 4 : 2
x = 2
Trả lời:
\(2x-3+5=6\)
\(\Leftrightarrow2x+2=6\)
\(\Leftrightarrow2x=4\)
\(\Leftrightarrow x=2\)
Vậy\(x=2\)
Hok tốt!
