Which is the most efficient way to solve this equation?

x+4=17

CLEAR CHECK

Subtract 4
from both sides because that will result in an equivalent equation with x
alone on one side.

Add 4
to 17
because x
equals 21
.

Subtract 17
from both sides of the equation so all terms will be on the same side of the equal sign.

Nothing, because the equation is already solved.

Answer 1
