You can't simplify it any further than 3x+2y+6z=24, unless you have been given values of x,y and z or other equations to find x,y and z.
10x + 41y - 142x + 2y = 10x - 142x + 41y + 2y = (10 -142)x + (41 + 2)y = -132x + 43y
It is y+3y-2y = 2y simplified
5+y+2y? = 5+3y?
Y plus Y = 2Y simplified

6 - y + 5y - 6y = 6 - 2y
You can't simplify it any further than 3x+2y+6z=24, unless you have been given values of x,y and z or other equations to find x,y and z.
5x+2x-3y+y = (5+2)x+(-3+1)y = 7x - 2y
10x + 41y - 142x + 2y = 10x - 142x + 41y + 2y = (10 -142)x + (41 + 2)y = -132x + 43y
-2y+y = -y
The equation can be simplified to show a value of Y in terms of X. 3X + 2Y +2 = 4Y + 4 3X + 2 = 2Y + 4 3X -2 = 2Y and 2Y = 3X - 2 means that Y = (3/2 X) -1
Solution: 2y + 4 = 3 + y Combine like terms: 2y - y = 3 - 4 Simplify further: y = -1

(2y + 1) + (y^2 + 1) = 2y + 1 + y^2 + 1 = y^2 + 2y + 2
