`(x+5)+25=125`
`x+5=125-25`
`x+5=100`
`x=100-5`
`x=95`
\(\left(x+5\right)+25=125\)
\(\Rightarrow x+5=125-25\)
\(x+5=100\)
\(x=100-5\)
\(x=95\)
(x + 5) + 25 = 125
x + 5 = 125 - 25 = 100
x = 100 - 5 = 95
\(\left(x+5\right)\) \(+25\) \(=125\)
\(x+5\) \(=125-25\)
\(x+5\) \(=100\)
\(x\) \(=100-5\)
\(x\) \(=95\)
