Answer: x = 10
Step-by-step explanation: To solve for <em>x</em> in the equation you see here, our goal is to get <em>x</em> by itself on one side of the equation.
Our first step will be to isolate the term containing <em>x</em> which in this case is 4x. To isolate 4x, we have to get rid of the +5 by subtracting 5 from both sides of the equation.
On the left, +5 -5 cancels and we're left with 4x. On the right, 45 - 5 simplifies to 5.
So our equation now reads 4x = 40.
To get <em>x</em> by itself since it's being multiplied by 4, we just divide both sides of the equation by 4. On the left, the 4's cancel and we're left with <em>x</em>. On the right, 40/4 simplifies to 10 so our answer is <em>x = 10</em>.
