Elimination method 5x+3y=-6 -4x-5y=-3

The correct answer is (-3, 3)

Step-by-step explanation:

In order to use the elimination method, multiply the top equation by 4 and the bottom equation by 5. Then add them together.

20x + 12y = -24

-20x - 25y = -15

-13y = -39

y = 3

Now that we have the value of y, we can plug it into either equation to get the final answer.

5x + 3y = -6

5x + 3(3) = -6

5x + 9 = -6

5x = -15

x = -3

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
