Answer:

Step-by-step explanation:
Given the system of two equations:

Multiply the first equation and the second equation by 60 to get rid of fractions:

Now multiply the first equation by 4 and the second equation by 5:

Subtract them:

Substitute it into the first equation:

The solution is
M = (-9 - 3) / (-5 - -2)
m = -12 / -3
m = 4
The slope is 4.
The solution of the inequality is t<-3. Because -15 divided by 5t is equal to -3
The answer is x=3 you (18-12=6/2=3)
