Question

Subtract 5y-8 from 2y+8

Answer 1

Subtract 5y - 8 from 2y + 8

To subtract two numbers, we can do it like this:

10 - 4 = 10 + (-4)

That is, add the first number with the second number with its sign changed. For simple numbers, it does not make much difference, but for algebraic expressions, it can help a lot.

To subtract both binomials, we write the first plus the second with changed signs:

2y + 8

-5y + 8

---------------

-3y + 16

The result of the subtraction is -3y+16
