Answer:
D. Multiply the second equation by 3. The solution is x = 12, y = 10.
Step-by-step explanation:
In order to cancel the +3y term in the first equation, the second equation's y-term (-y) must be multiplied by a value that makes it be -3y. The second equation must be multiplied by 3.
__
That answer choice also has the correct values for the solutions to x and y.
Answer:
(6 * 1/101) + (8 * 1/102) 0.68 = (6 * 1/10) + (8 * 1/100) 0.68 = 6/10 + 8/100. 0.68 = 0.6 + 0.08.
