Answer:
x=-3
Step-by-step explanation:
2x+7=4+x
2x-x+7=4
x+7=4
x=4-7
x=-3
C(x) = 300.
Our question becomes simple: 300 = x^2-40x+610
x^2-40x+610-300 = 0
x^2-40x+310 = 0
Now find the value for x with either the quadratic formula or by factorization.
Let me know how it goes. Giving the full answer won’t help you improve
You're on the right track. Start by combining like terms on the left side of the equation by adding 56 and 34.
90 = n + 30, now subtract 30 from both sides of the equation to isolate the variable n.
60 = n is the answer.
Answer:
The first one is x=-y-2z-7
The second one is x=-1/3y + 1/3z + -4/3
The third one is x= 3y + 2z + 17
