f(x)= (4 - 5y)/8 f(y)= (4 - 8x)/5
10x - 5y + 2x - 3y = 12x - 8y
They add to x+4y simplified
Without an equality sign the given terms can't be considered to be an equation.
No.
45
3x+5y+8x+2y combine 3x and 8x to get 11x 11x+5y+2y combine 5y and 2y 11x+7y is the answer.
If you mean 8x+5y = 100 then it is a straight line equation
-8x-5y-45 is not an equation. An equation requires an equal sign in there somewhere. If you meant -8x-5y=45, then there are many ways to rewrite it, such as -(8x+5y)=45, or 8x+5y=-45, or 8x=-(45+5y), to name three. If you meant -8x-5y=-45, then you're probably looking for 8x+5y=45.
8x + 20y
f(x)= (4 - 5y)/8 f(y)= (4 - 8x)/5
x=0 y=2
10x - 5y + 2x - 3y = 12x - 8y
16x-8x+12 = 78+22 16x-8x = 78+22-12 8x = 88 x = 11
(8x + 5y)(64x^2 - 40xy + 25y^2)
