That's the identity property of addition. Anything plus zero equals what you started out with.
x = 0
y equals x plus 4 when y equals 0 then x equals 2i i is the square root of negative 1
It doesn't; it equals 2x. Only if x = 0 does 2x = x.
0
89+x=x 89=x-x 89=0 Therefore, "No solution".
x = y = 0 ?
x=0
If 40 plus x equals 25 then x is equal to -15.
it equals 3.
Six equals x is the answer.
x = 0
It equals x+5y simplified
