### Solve the system of equations using substitution method $$7x+10y=36$$ $$-2x+y=9$$

$$x=2, y=5$$
$$x=-2, y=5$$
$$x=-2, y=-5$$
$$x=2, y=-5$$

### Solve the system of equations using substitution method $$x+y=6$$ $$-3x+y=2$$

$$x=1, y=5$$
$$x=-1, y=5$$
$$x=1, y=-5$$
$$x=-1, y=-5$$

### Solve the system of equations using substitution method $$x-7y+11=0$$ $$5x+2y=-18$$
