Question

EMERGENCY
i+i+i+i=-8
i=

Answer 1

i=2

Explanation:

i+i+i+i=8

4i=8

i=8/4

i=2

Answer 2

i + i + i + i= -8
First, combine like terms (i’s)
4i=-8
Divide both sides by 4 to isolate i
4i=-8
—- —-
4 4

i=-2

You can plug this back in to see if it works.

(-2) + (-2) + (-2) + (-2) = -8

-8=-8

Therefore, i= -2
