This is a linear equation in two variables and the coordinates of each and every point on the line that it describes is a solution.
A single linear equation does not have an "answer".

x=4 y=4
x = y = 0 ?
Symmetry, which states that if A = B then B = A Put A = 4 and B = x + y
x = 2y = 4
8
x=4 y=4
x = y = 0 ?
x = 0 and y = 4
y equals x plus 4 when y equals 0 then x equals 2i i is the square root of negative 1
symmetric property
Symmetry, which states that if A = B then B = A Put A = 4 and B = x + y
If X+Y=5;X=4, then x=4 and y=1
x + 3y = 4 -x + 2y = -4 Simultan eous eq'ns. Eliminate 'x' by adding. 4 Hence 5y = 0 y = 0 When y = 0 Substitute x + 3(0) = 4 x + 0 = 4 x = 4 So the answer as a coordinate pairs is ( x,y) = ( 4,0)
4
x=4 y=x+3 y=4+3 y=7
x = 2y = 4
