Tilda writes the equation 5y=20x+8
. She wants to rewrite the equation in terms of x
. After subtracting 8 from both sides of the equation, what number should she divide both sides of the equation by in order to accomplish this goal?
In order to rewrite the equation in terms of x, Tilda needs to isolate the term with x on one side of the equation.
To accomplish this, Tilda subtracts 8 from both sides of the equation:
5y - 8 = 20x
Now, to isolate x, Tilda needs to divide both sides of the equation by a number.
To determine this number, Tilda needs to reference the coefficient of x, which is 20. Therefore, she needs to divide both sides of the equation by 20.
Dividing both sides of the equation by 20, she gets:
(5y - 8)/20 = x
Therefore, Tilda should divide both sides of the equation by 20 in order to rewrite the equation in terms of x.
To rewrite the equation 5y = 20x + 8 in terms of x, Tilda needs to isolate the variable x by itself on one side of the equation.
To do that, Tilda should start by subtracting 8 from both sides of the equation:
5y - 8 = 20x + 8 - 8
5y - 8 = 20x
Now, Tilda needs to divide both sides of the equation by 20 in order to isolate x:
(5y - 8) / 20 = (20x) / 20
(5y - 8) / 20 = x
Therefore, Tilda should divide both sides of the equation by 20 in order to rewrite the equation in terms of x.
