To move it to the other side, carry the opposite operation. So add the one on both sides.

Answer 20

Answer 21

EXAMPLE NOT YOUR MATH PROBLEM

y + 2 = 4
^
isolate the variable
y + 2 on the left of the = sign
you want to make it just
"y"

how is this done
y+2 + (-2) = 4 + (-2)
add a -2 on both sides of the equation

(whatever is done on one side of the equation must be done on the other side of the = sign)

y = 2
