3(x-4)=6(2x+1)

so now first well multiply 3 by x and 4 and 6 by 2x and 1 .

3x-12=12x+6

-6-12=12x-3x

-18=9x

-18/9=x

x=-2

Alright so first let's look at what we have.

First work away the brackets, for example;

\$\$3(x-4) = 6(2x+1) \Rightarrow 3x-12 = 12x+6\$\$

Now substract \$\$12x\$\$ from both sides

\$\$-9x-12 = 6\$\$

\$\$-9x = 18\$\$

Divide both sides by -9

\$\$x = -2\$\$

voila!

Hi Rosala,

Reinout is right!

Use your edit button to fix your post (minus signs are missing)

also get rid or the extra = signs at the beginning of your lines and then I'll give you thumbs up!

It would be even better Rosala if you deleted the equal signs at the begining of each line.

There should only be one equal sign per line!

Oh Reinout - I love your rooster - he is  VERY talented!
