=3y-11, 4x-3y=-26 Substitution
Answer:
x=10
Step-by-step explanation:
16+2x=36
subtract 16 from both sides
2x=20
divide 2 from both sides
x=10
Answer:
Step-by-step explanation:
If
, then 
Now, puting
value in the other equation, we have

Therefore, is a cubic equation
(f + g)(x) = 7x + 6 + 4x² = 4x² + 7x + 6
The notation given means to add the rules of f(x) and g(x), and since there are no like terms, your answer is 4x² + 7x + 6
