\(2\times\left(x-5\right)-17=25\)
\(2\times\left(x-5\right)=25+17\)
\(2\times\left(x-5\right)=42\)
\(x-5=42:2\)
\(x-5=21\)
\(x=21+5\)
\(x=26\)
2 * ( x - 5 ) = 25 + 17
2 * ( x - 5 ) = 42
x - 5 = 42 : 2
x - 5 = 21
x = 21 + 5
x = 26
Trả lời:
\(\rightarrow\)2 x ( x - 5 ) = 25 + 17
\(\rightarrow\)2 x ( x - 5 ) = 42
\(\rightarrow\)x - 5 = 42 : 2
\(\rightarrow\)x - 5 = 21
\(\rightarrow\)x = 21 + 5
\(\rightarrow\)x = 26
