Answer:
t=-2
Step-by-step explanation:
(t+9)20=140
Distribute the 20
20t +180 = 140
Subtract 180 from each side
20t +180-180 = 140-180
20t = -40
Divide by 20
20t/20 = -40/20
t=-2
Answer:
D.
Step-by-step explanation:
In order to eliminate, the numbers must eliminate. If the second equation is multiplied by 3, then the 3 and the -3 can be eliminated. Since it is multiple choice, we can plug in x = 12 and y = 10 to see if they are correct. 12 + 30 = 42 and 24 - 10 = 14, so D is correct.
