Answer:
x=6
y=1
Step-by-step explanation:
3x=18, so when you divide 3x by 3 to get x alone, you also divide the other side and 18 divided by 3 is 6. now you know that x equals 6. then you plug x back into either equation to solve for y. I chose to plus into x-3y=3. it would read 6-3y=3. you then subtract 6 from both sides and get that -3y=-3. therefore when you divide both sides by -3, you get that y=1
