Multiply the first equation by 4 (so that both equations will have 8x terms) and then subtract:
8x-20y = -24
8x +3y = 68
------------
0 -23y = -92
Now divide both sides by -23:
y = 4
Find x by plugging y=4 into either equation:
8x +3(4) = 68
8x = 68 - 12
8x = 56
x = 7
So the answer is ordered pair is (7,4)
Answer:
n = 0
Step-by-step explanation:
To solve this equation, we would have to get it into the form n = _. That would be our answer.
56n + 36n = 0
Combine like terms. 56n + 36n turns into 92n.
92n = 0
Divide both sides by 92 to get rid of the coefficient of 92 on the left side. On the right side, 0 divided by 92 is still 0.
n = 0
The solution to the equation would be n = 0.
