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.
