Answer:
1)x=6
Step-by-step explanation:
step 1: add 2x to both sides.
x−15+2x=−2x+3+2x
3x−15=3
step 2: add 15 to both sides.
3x−15+15=3+15
3x=18
step 3: divide both sides by 3.
3x/3=18/3
x=6
answer:
x=6
good luck :)
hopefully, this helps

Answer:
178/7
Step-by-step explanation:
4x-7+3x+9=180
4x+3x-7+9=180
7x-7+9=180
7x+2=180
7x=180-2
7x=178
x=178/7
Answer: B
Step-by-step explanation:
(f+g)(x) means f(x)+g(x). It is saying to add f(x) and g(x). Since we were given f(x) and g(x), we can directly add them together.
(f+g)(x)=4x+2+x²-6 [combine like terms]
(f+g)(x)=x²+4x-4
Now that we have found (f+g)(x)=x²+4x-4, the answer is B.
