4y+y=10
5y=10
y=2
That is called an equation. Any time a certain amount of numbers equals another number, that is called an equation. This is a perfect example of one, as 10 does in fact equal 10.
It equals a simple linear equation in 'y'. Its solution is 7/3 .
-10 plus 10 equals 0.
The equation is -2y + 16 = 10
That word "equals" in there makes it an equation.

-2x + 8 = 7x - 10 is technically an equation, in and of itself.
-2
y is the variable
sixty is equal to 10 plus 50, and as 10 equals 50, and 50 equals 79, then it would be fair to assume that 60 equals 50 plus 79, which is 129.
