Answer:
Solution x = - 1
Step-by-step explanation:
3 / (2x+1) = 9 / 3x
Cross multiply
3(3x) = 9(2x + 1)
Distributive property
9x = 18x + 9
Subtract 18x from both sides
-9x = 9
Divide both sides by -9
x = -1
Answer:
m= -3
Step-by-step explanation:
slope intercept formula
(y2-y1)/ (x2-x1)
-6-3= -9
-2-1=-3
-9/3 =-3
