25 + ( 15 + x) = 125
15 + x = 125 - 25
15 + x = 100
x = 100 - 15
x = 85
\(25+\left(15\times x\right)=375:3\)
\(25+\left(15\times x\right)=125\)
\(\left(15\times x\right)=125-25\)
\(\left(15\times x\right)=100\)
\(x=100:15\)
\(x=6\left(dư10\right)\)

25 + ( 15 + x )= 375 : 3
=> 15 + x = 125 - 25
=> x = 100 - 15
=> x = 85
---> 25 + 15 + x = 375 : 3
---> 40 + x = 125
---> x = 125 - 40
---> x = 85
