12x-8y
9y+3 = 5y+13 9y-5y = 13-3 4y = 10 y =2.5
(6x)(5y)
2x + 3y - x + 5y combine the like terms 2x - x + 3y +5y simple arithmetic x + 8y
Well, isn't that a happy little math problem we have here? To solve 3x + 5y, you just need to combine like terms. You can't add x and y together, so the expression stays as 3x + 5y. Just remember, there are no mistakes in math, only happy little accidents!
y=4
5y + 5y = 10y
11x + 5y
It is: 7x+10y
The Abelian property or commutativity.
12x-8y
5y+8
The multiplicative inverse of 5y -xy + 1 is 1/5y -xy + 1 The additive inverse of 5y - xy + 1 is -5y + xy - 1
The Commutative Property of Addition.
3x+5y+8x+2y combine 3x and 8x to get 11x 11x+5y+2y combine 5y and 2y 11x+7y is the answer.
It is an expression that can be simplified to 5y+2x-6
The math equation -13 plus 3-Y 15 equals to 5Y+25. This is learnt in college.
