2y^2+5y+2=(2y+1)(y+2)
The Abelian property or commutativity.
5y = 2y+9 5y-2y = 9 3y = 9 y = 3
x + 2y = 2.90 => x = 2.90 - 2y Substitue this value of x in the other equation: 3x + 5y = 7.60 3*(2.90 - 2y) + 5y = 7.60 8.70 - 6y + 5y = 7.60 1.10 = y and then substitute this value of y in either equation to find x: x = 2.90 - 2y = 2.90 - 2*1.10 = 2.90 - 2.20 = 0.70 Solution: (x, y) = (0.70, 1.10)

X = -2(13 + y) / 3x = 5y / 4 - 1
(14x-2y)+(7x-3y)+(-3x) = 14x-2y+7x-3y-3x =(14+7-3)x-(2+3)y =18x-5y
To simplify the expression 13x + 2y - 10x - 7y, you first combine like terms. Group the x terms together and the y terms together: (13x - 10x) + (2y - 7y). This simplifies to 3x - 5y. Therefore, the simplified expression is 3x - 5y.

2y^2+5y+2=(2y+1)(y+2)
The Abelian property or commutativity.
5y-2y= 3y+2 5y-2y-3y= 2 0y= 2
5y = 2y+9 5y-2y = 9 3y = 9 y = 3
If you mean: 13x+2y-10x-7y then it is an algebraic expression that can be simplified to 3x-5y
x + 2y = 2.90 => x = 2.90 - 2y Substitue this value of x in the other equation: 3x + 5y = 7.60 3*(2.90 - 2y) + 5y = 7.60 8.70 - 6y + 5y = 7.60 1.10 = y and then substitute this value of y in either equation to find x: x = 2.90 - 2y = 2.90 - 2*1.10 = 2.90 - 2.20 = 0.70 Solution: (x, y) = (0.70, 1.10)
