Answer:x=4 and y=4
Step-by-step explanation: if you divide 9 by 3 it would be 3 and 6 divided by 3 would be 2 so if you multiply 2 by 4 and 3 by 4 and you add them together it will equal 20
Answer:
x=-8,y=-2
Step-by-step explanation:
x=2+5 y
put value of x in eq 2
9(2+5 y)+8=32 y
18+45 y+8=32 y
26=32 y-45 y
26=-13 y
y=26/-13
y=-2
put value of y in eq x=2+5 y
x=2+5(-2)
x=2-10=-8
So, first you need to think 'what is the highest degree?'
Then you need to figure out how many terms you have
polynomial- four or more terms
trinomial- three terms
binomial- two terms
