Write the equation 2y-4x=5 In the form y=my+b
Vika [28.1K]

Answer:

y = 2x + 2.5

Step-by-step explanation:

To begin, we start with the equation 2y - 4x = 5.

We will add 4x to both sides to move the x term to the right side of the equation, giving us:

2y - 4x + 4x = 4x + 5

2y = 4x + 5

Next, we should divide by 2 to cancel out the coefficient on the y-term and isolate it on the left side of the equation:

2y/2 = 4x/2 + 5/2

y = 2x + 5/2

Therefore, your answer is y = 2x + 5/2 or y = 2x + 2.5.

Hope this helps!
