When you have an equation with an unknown variable, your goal is to find the value of x. You can do that by isolating the variable on one side of the equationFor example, if you have the equation 5x + 9 = 44
To isolate the x, you need to move the 9 to the other side of the equation by subtracting 9 from both sides of the equation (5x = 35)
To solve for x, now, you need to move the 5 by dividing both sides of the equation by 5
