If you mean: -8y-(x-4x)+3y then it is 3x-5y simplified
4x + 5y = -8 is an equation with two variables. While you can solve for y = something, you won't come up with a single number. For example, 4x + 5y = -8 5y = -4x - 8 y = -4x/5 - 8/5. And you can do the same for x = something in terms of y.
I can't tell what sign is before 5y, so I'll assume +. 4x+5y=7. Double this is 8x+10y=14, triple is 12x+15y=21. etc
If: 3x-5y = 25 Then: -5y = -3x+25 And: y = 3/5x-5 So: slope is 3/5 or 0.6 and the y intercept is -5

no, 4x-3y=11x 3x-5y doesn't equal -11
It is: 7x+10y
Well, the way you wrote it, you would have:(4x - 5y - 3) x 3x + 5ywhich would give12x^2 - 15xy - 9x + 5yBut, if you meant the quantity (3x + 5y), then you would have:(4x - 5y - 3) x (3x + 5y)which would give12x^2 - 15xy - 9x + 20xy - 25y^2 - 15yand combining terms12x^2 - 25y^2 + 5xy - 9x - 15y
X = -2(13 + y) / 3x = 5y / 4 - 1
If you mean: -8y-(x-4x)+3y then it is 3x-5y simplified
If you mean: 3x+2y = 6 and -4x+5y = 15 then it works out as x = 0 and y = 3
xy(7+2y-3x)-6xy
(2, 2)
p + q + r = (2x - 9y) + (5y + 6 - 4x) + (3x + 3y - 5) = x - y + 1
If: 4x = 5y Then: x = 5y/4
You move one of the like terms to the other side using algebraic operations. For instance... 3x + 5y = 7x + 3 ... and you want to solve for x ... ... first, subtract 3x from both sides ... 3x - 3x + 5y = 7x - 3x + 3 5y = 4x + 3 ... do I need to explain further???
2x+5y+2z-3w=3 3x+6y+5z+2w=2 4x+5y+14z+14w=11
