Answer:
r= 2.5 and s=3
Step-by-step explanation:
2r plus 6r equals 8r
-3s and 3s cancell eachother out
and 14 plus 6 is 20
with leaves us with
8r=20
20 divided by 8 is 2.5
now we go back to the orginal problems
2 times 2.5 is 5
14 minus 5 is 9
9 divided by 3 is 3
so s=3
but to check this all you would use r=2.5 and s=3 in the othe equsion
6 times 2.5 is 15
and -3 times 3 is -9
15-9= 6
