Answer:
4 * x/y = 20
x = 5y
Step-by-step explanation:
step 1: multiply 4 by x/y
ex: 4 * x/y = 20 (4x/y = 20)
step 2: multiply y on both sides of the equation
ex: 4x/y * y = 20 * y (4x = 20y)
step 3: divide both sides of the equation by 4
ex: 4x/4 = 20y/4 (x = 5y)
step 4: take the answer for x which is 5y and input it into the original equation to check your answer
ex: 4 * 5y/y = 20
20y/y = 20
20y = 20y (if both sides of the equation are the same number like 20y = 20y then your answer is true)
