-4(0) + 0 = 2 ??
That's not possible! See
-4(0)=0
-> 0=2
Suppose we want to find the value of y when x=0
-> -4(x=0)+y = 2
-> -4*(0) + y = 2
-> 0 + y=2
-> y=2
Now, what if y=0? What would the value of x be? Let's find out!
-4x + (y=0) = 2
-> -4x + 0 = 2
-> -4x=2
-> -4x (-1/4) = 2(-1/4)
-> x=-2/4
-> x= -1/2
