Answer:
x = 3; y = -6
Step-by-step explanation:
x - 2y = 15
2x + 4y = -18
Multiply both sides of the first equation by 2. Write the second equation below it, and add the two equations.
2x - 4y = 30
(+) 2x + 4y = -18
---------------------------
4x = 12
4x/4 = 12/4
x = 3
Now we substitute 3 for x in the first equation and solve for y.
x - 2y = 15
3 - 2y = 15
-2y = 12
y = -6
Answer: x = 3; y = -6
Answer:
2
Step-by-step explanation:
3x + 7=15 -x
4x= 8
x= 2
3*2 + 7 = 15-2
Answer:
8 students received an A.
Step-by-step explanation: 1/3*24=8
Given:
6 . ln x = 9.1
We are asked to find the solution of the above equation leaving the answer to two decimal places.
6lnx = 9.1
Let's divide both sides by 6
6linx/6 = 9.1/6
6 cancelling out on the left hand side.
lnx = 9.1/6
linx = 1.5166
x = e^1.5166
x = 4.5570
x = 4.56 (to two decimal places).
The correct option is A, which is x = 4.56
