solve for x:3(6x+3)-2(x-3)=0

Question

please solve step by step

Answer 1

Crista:

 

The first thing you should do is eliminate the parentheses by distributing the factor outside, as follows:

 

3*6x+3*3-2x+6=0

18x  + 9  -2x+6=0

 

Next, collect like terms and simplify:

 

18x-2x+9+6=0

16x+15=0

 

Now, Subtract 15 from both sides to isolate the x term:

 

16x+15-15=0-15

16x          =  -15

 

Finally, divide both sides by 16:

 

(16x)/16  =  -15/16

    x         =  -15/16

 

Hope this helps.
