C because it has an equal number of y's on each side so to solve it you would subtract 4y from both sides leaving:
5 = -6
which is not possible so there is no solutions.
Answer:
38.6
Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask
5x + 2y = 12
-6x - 2y = -14
Add them
-x = -2
x = 2
5x + 2y = 12
(5*2) + 2y = 12
10 + 2y = 12
2y = 2
y = 1
I am fairly certain it’s C 1.07X since that would include both the tax and its original price
We can solve this question easiest by putting it as 2 equations.
First, well put the original equation, 2c+5b=55,000. B stands for the cost of backyard pool weddings and c stands for the cost of carribean weddings.
We got this equation because the question states that there were 2 carribean weddings and 5 pool weddings, and the amount of money obtained was $55,000 total as a result.
Now, we’ll put the extra information into an equation, c-10,000=b. We got this equation because it clearly states that backyard pool weddings cost 10,000 less than Caribbean, so c-10,000=b.
Now, we have to solve. Since the first equation has 2 variables, it is unsolvable. This is where the second equation comes in. We can rewrite c-10,000=b as b+10,000=c.
Now, since b+10,000=c, substitute b+10,000 for c in the first equation.
The result is 2(b+10,000)+5b=55,000.
Now that we only have one variable in the equation, it is solvable.
20,000+7b=55,000
7b=55,000
B=7,857
Now to solve for c, insert 7,857 for b in the second equation.
7,857+10,000=c
17,857=c
The cost of carribean weddings was $17,857.
The cost of a backyard pool wedding was $7,857.
Hope this helps!
