3x-2=2x-7
We simplify the equation to the form, which is simple to understand
3x-2=2x-7
We move all terms containing x to the left and all other terms to the right.
+3x-2x=-7+2
We simplify left and right side of the equation.
+1x=-5
We divide both sides of the equation by 1 to get x.
x=-5
N+(n+2)+(n+4)=51
Which isn't possible because an even plus an even equal even!
The answer to your problem would be 2Y +3x=6
