Answer:
2(n+3) = n-9
Step-by-step explanation:
Step 1: Multiply (n+3) by two; 2n + 6
Step 2: Subtract n on both sides; n+6= -9
Step 3: Subtract 6 on both sides; n= -9 - 6
Step 4: Add -9 and -6; -15
Solution: n= -15
b
Slope intercept form: y= −5 7 x+5
The graphing points would be (0,5)(7,0)
x=1
y = -3 when x = 4
2x-4y = 20
x = 4
2(4) - 4y = 20
8 - 4y = 20
-4y = 12
y = -3
