Question

3(x-1)=9+x

Answer 1

These are linear equations and in this type of equation the process to solve is to split the variable to a side.

Here if we take all the x terms to the right side we will get,

3x-x=9+3
=>2x=12
dividing both sides by 2 we will get
x=6

Answer 2

thank you so much!!!!

Answer 3

welcome. These are not that hard stuff, all you need is practice. But remember to split the variables in linear equations.
