To solve for y in the equation 10x + 5y = -20, we need to isolate y on one side of the equation.
First, let's subtract 10x from both sides:
10x + 5y - 10x = -20 - 10x
This simplifies to:
5y = -20 - 10x
Next, divide both sides by 5 to solve for y:
5y / 5 = (-20 - 10x) / 5
y = (-20 - 10x) / 5
Therefore, the equation in terms of y is:
y = (-20 - 10x) / 5
