1) (x,y) = no solution
2) x=-2y
-2y-y = 9
-3y = 9
y = -3
x = -2(-3)
x = 6
(x,y) = (6,-3)

Answer:
m = 13.
Step-by-step explanation:
Recall that adding logarithmic equations, (ex: log a + log b) is the same as log (a·b). Therefore:
log 12 + log 5 = log (4m + 8)
log (12·5) = log (4m + 8)
log (60) = log (4m + 8) **Ignore 'Log' to solve for 'm'
60 = 4m + 8 **Subtract both sides by 8
52 = 4m **Divide both sides by 4
m = 13.
Answer:
4
Step-by-step explanation:
9 x 2 Is 18 so you would multiply 2 x 2 as well
