Step-by-step explanation:
5+6x=2x-7
We simplify the equation to the form, which is simple to understand
5+6x=2x-7
We move all terms containing x to the left and all other terms to the right.
+6x-2x=-7-5
We simplify left and right side of the equation.
+4x=-12
We divide both sides of the equation by 4 to get x.
x=-3
