If you do not know what y is equal to then you can not evaluate this. If it is equal to zero then y is equal to 6/5.
5y=25x 25x=5y -5y 25x-5y=0
5y
5y-3y = 2
If the inequality is > (greater than) or >= (greater than or equal to), then there are an infinite number of solutions. So let the inequality be < (less than) or <= (less than or equal to) x = 1: 5y <= 16 so y = 1, 2 or 3 x = 2: 5y <= 12 so y = 1 or 2 x = 3: 5y <= 8 so y = 1 x >= 4: 5y <= 4 no solution. So whether the inequality is < or <= there are 6 ordered pairs.

It equals x+5y simplified
5y + 24 = 29 5y = 5 (subtract 24 from both sides) y = 1 (divide by 5)
-8-5y = 12-9y 9y-5y - 12+8 4y = 20 y = 5
-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.
If you do not know what y is equal to then you can not evaluate this. If it is equal to zero then y is equal to 6/5.
no, 4x-3y=11x 3x-5y doesn't equal -11
6y + 5y = -66 11y = -66 (-66/11 = y) y = -6
-3
If 3x, 5y and 7z are equal terms, them each of them will equal one third of 357, or 119. 3x = 119 x = 39 and 2/3 5y = 119 y = 23 and 4/5 7z = 119 z = 17
5Y - X = 11 ( the 1 coefficient is always implied, not written )5Y = X + 11Y = (1/5)X + 11/5m(slope) = 1/5===========
5y + 5y = 10y
