Answer:
5x + 6y = 20_____(1)
8x - 6y = -46_____(2)
Solving simultaneously:
Eqn(1) + Eqn(2)
5x + 8x + 6y + (-6y) = 20 + (-46)
13x = -26
x = -2
substituting this into Eqn (1):
5(-2) + 6y = 20
-10 + 6y = 20
6y = 30
y = 5
hence:
x = -2,y = 5.
Answer:
if u put a penny in a microwave it change color u should try
3x^5 - 8x^3 - 2x^2 + 5
ur terms are : 3x^5 and -8x^3 and -2x^2 and 5
so u have a polynomial with 4 terms
