Answer:
Step-by-step explanation:
Step 1:
Isolate x (1st Equation)
2x + 3y = 0
<u> - 3y = -3y</u>
2x = -3y
Step 2:
Divide both sides by 2
x = -3y/2
Step 3:
Replace the x from 8x with -3y/2 and Solve the equation
8(-3y/2) + 9y = 18
-12y + 9y = 18
-3y = 18
y = -6
Step 4:
Go back to the 1st equation and replace the y from 3y with -6. You are now solving for x. Solve the equation.
2x + 3(-6) = 0
2x - 18 = 0
<u> + 18 = +18</u>
2x = 18
x = 9
Step 5:
Write your final answer.
(x, y) = (9, -6)
Yes of course u divide 10 into 120 which is 1/12
Answer:
1,000,000,000
Step-by-step explanation:
1 kilometer is equal to 1000 meters, and 1 is 1 km * 1 km * 1 km
Therefore,
1000m * 1000m * 1000m = 1,000,000,000
Hope this answer helped! :)
