Answer: 20-2x/-4
Step-by-step explanation:
To actually solve for y as a number, you need two equations.
For this case move the 2x to the other side, making the equation -4y=20-2x.
Then divide by -4 on each side making the equation y=20-2x/-4.
Answer:
y = 20-2x /-4
Step-by-step explanation:
Given 2x - 4y =20
y ?
Subtract 2x from both sides of the equation
2x - 2x -4y = 20 - 2x
-4y = 20 - 2x
Divide both sides by -4
-4y/-4 = 20-2x / -4
y = 20-2x /-4
