SSolve for x.<br><br> 9(x + 1) = 25 + x<br><br> x = 2<br> x = 3<br> x = 4<br> x = 5
Zepler [3.9K]
Given,

9(x+1) = 25 + x

expanding,

9x + 1 = 25 + x

bringing x to left hand side and taking 1 to right hand side with change in their respective signs,

9x - x = 25-1

=> 8x = 24

transposing 8 ,

=> x = 24/8 = 3

Hence x = 3
