You only know. The n stands for the term number.
Pretty sure it’s D and F because if you set (x-4)=0, x is 4 and if you set (x+7)=0, x is -7
Answer:
x=47, y=68
Step-by-step explanation:
Add the two equations. Then we get
-y=-68
y=68
Substituting the value of y in the first equation,
8x-6(68)=-32
8x-408=-32
8x=376
x=47
I’m not sure i’m pretty sure it’s 28
