Answer 2

To solve the equation 42y - 56 = 3y - 78, we'll begin by isolating the variable "y" on one side of the equation. Here are the steps:

42y - 56 = 3y - 78

First, let's simplify the equation by combining like terms:

(42y - 3y) - 56 = -78

39y - 56 = -78

Next, we'll move the constant term (-56) to the other side of the equation by adding 56 to both sides:

39y - 56 + 56 = -78 + 56

39y = -22

Finally, to solve for "y," we divide both sides of the equation by 39:

39y/39 = -22/39

Simplifying further:

y = -22/39

Therefore, the solution to the equation 42y - 56 = 3y - 78 is y = -22/39.
