y=x+4
x = 0 and y = 4
y=2x-4 y=2x-5 y=1 1=2x-4 -2x = -5 x=2/5 the solution is (x,y) = (2/5,1)
x=3
x = y = 3
y equals x plus 4 when y equals 0 then x equals 2i i is the square root of negative 1
x=4 y=4
0
-4
x = 0 and y = 4
y=x/4
0
x = -3, y = 7
It is (-1, 3).
No. -4 does not equal -2(1).
8
Y=4, X=1
y=2x-4 y=2x-5 y=1 1=2x-4 -2x = -5 x=2/5 the solution is (x,y) = (2/5,1)
