To solve for y, first add 4y to both sides of the equation:
10 - 4y + 4y = -40 + 4y
10 = -40 + 4y
Next, subtract 10 from both sides of the equation:
10 - 10 = -40 - 10
0 = -50 + 4y
Now, add 50 to both sides of the equation:
0 + 50 = -50 + 4y + 50
50 = 4y
Finally, divide both sides by 4 to solve for y:
y = 50 / 4
y = 12.5
Therefore, the solution to the equation 10 - 4y = -40 is y = 12.5.
10 - 4y = -40
