A is one solution, B is infinite, and c is none.
Subtract 5 from both sides.
Subtract 8n from both sides.
Divide both sides by -9 to solve for n.
The value of n is
-4/9.
Slope intercept form
y = mx + b
change it to standard form
ax +by = c
y = -1.7x + 8.5
1.7x + y = 8.5
multiply 10 on both side
17x + 10y = 85
hope this help
