Question 88064
{{{3x-5(3x-7)=2(x+9)+45}}}
First, let's simplify what we can, but multiplying through the parenthesis:
{{{3x-15x+35=2x+18+45}}}
Next, we want to put all the x terms on one side of the equation:
{{{3x-15x-2x=18+45-35}}}
Now we can combine the "like" terms:
{{{-14x=28}}}
Finally, solve for x:
{{{highlight(x=-2)}}}
TO check this, plug in -2 everywhere you see x in the original equation and be sure that the equality holds true.
I will leave that part to you.
Good Luck,
