It depends on the value of X
If we assume that the value of X is 22, then 22 + 4 = 26
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)
Sure does.
2x-4
x(x+4) equals x2 plus 4x
If the x=4, then its equivelent to 12 + 4, which equals 16.
symmetric property
4
y equals x plus 4 when y equals 0 then x equals 2i i is the square root of negative 1
(x + 4)(x +4) or (x + 4)squared
x=27
8
If x=4 then 2x+7 =
