How do you do 8y + 5 - 4y + 1 = 46

Y=10

Step-by-step explanation:

You need to isolate the variable "y"

To do this simply subtract the whole numbers, 5 and 1, from the left side of the equation and add the y values together.

This leaves you with "8y-4y=46-5-1" which simplifies to "4y=40"

Now you simply divide both sides of the equation by the number with the variable y, being 40/4, leaving you with "y=10"
