Answer 3

To solve the equation 7y - 4 = -7.5, follow these steps:

Step 1: Isolate the variable term (7y) on one side of the equation by adding 4 to both sides:

7y - 4 + 4 = -7.5 + 4

This simplifies to:

7y = -3.5

Step 2: To solve for y, divide both sides of the equation by 7:

7y / 7 = -3.5 / 7

This simplifies to:

y = -0.5

So the solution to the equation is y = -0.5.
