3x + 2y =25 is an equation, and the function f(x)=y= -1.5x + 12.5. I don't know what you mean by sum since x and y could equal different numbers.
you need another equasion... or you could re arrange it into a straight line formula. 3x + 2y = 25 2y = -3x + 25 y = -3/2x + 25/2
33
x2 + 2y = 52 + 2*2 = 25 + 4 = 29
2y+8y = 10y
This means that 2y - 3 = 2y + 4 which is not possible.
Sum Numb!

3y+5=y-25 2y=-30 y= -15
This means that 2y - 3 = 2y + 4 which is not possible.
No 2y-3 is not equals y plus 2AND how old are u?
(3, 2)
2y+26 = 28 2y = 28-26 2y = 2 y = 1
x + 2y = -5 2x + 3x = -9 5x = -9 x + 2y = -5 x = -2y - 5 5(-2y - 5) = -9 -10y - 25 = -9 -10y = 16 y = -5/8 x = -2y - 5 x = -2(-5/8) - 5 x = -5/4 - 5 x = -25/4 (-25/4, -5/8)
2y(x+2)=
