It's an algebraic expression that can be simplified to: x-5y
x - 5y = -4 x + 8y = -4 The first equation gives x = 5y - 4 SUBSTITUTE this value for x in the second equation: (5y - 4) + 8y = -4 Simplify: 13y = 0 so that y = 0 Then x = 5y - 4 gives x = -4
3y+5.2=2-5y 8y=-3.2 y= -0.4
8y-3x
x+8y=28 -3x+5y=3
7 + 8y - 3y + 2 =7 + 2 + 8y - 3y = 9 + 8y - 3y = 9 + 5y
3x - 8y + 2x - 5 - 5y = 5x -13y - 5

If you mean: -8y-(x-4x)+3y then it is 3x-5y simplified
7y - 6 = 5y - 147y - 5y = 6 - 142y = -8y = -8 ÷ 2y = -4
It is: x-5y simplified
