$2x7=5x+6$. We'll solve this equation in steps: 1 Get rid of $2x$ by subtracting $2x$ in both sides: $(2x7)2x=(5x+6)2x$ 2Get rid of brackets and put numbers having x's one next the other: $2x2x7=5x2x+6$ 3You see that $2x2x=0$ and $7$ is left alone. In the other side $5x2x=3x$. 4From step $3$ the equation rearranges to: $7=3x+6$. 5We must cancel out $6$ in this step. To do so, we add the opposite of $6$ in both sides, which is $6$: $76=3x+66$. Note that $66=0$. 6The equation becomes: $13=3x$ or $3x=13$ 7Get rid of $3$. To do so, divide both sides by $3$: $\dfrac{3x}{3}=\dfrac{13}{3}$. Note that $\dfrac{3x}{3}=\dfrac{3}{3}x=1*x=x$. $x=\dfrac{13}{3}$ Hope that helped. Last edited by Assayid; June 2nd, 2015 at 10:35 PM.

Well, I pointed to a link out of general help, and mods banned me seeing it as a commercial spam.

Well Mathlover, I see you "live nowhere"; perhaps you can move to Banned Camp" too?!
