Answer:
7(x+3)
Step-by-step explanation:
7x+21
7x = 7*x
21 = 7*3
We can factor out a 7 from both terms. What remains is what is inside the parentheses
7(x+3)
B) y = 5x + 15 and y = -5x + 15 I think.
I got you, just follow my work
-2x+3=-5x+9
-2x=-5x+6
3x=6
x=2
Plug x back in
-2(2)+3= -1
y=-1
FINAL ANSWER: (2,-1)
