7720 + 80x = 3200 + 120x
I think this is correct. Hope it helps!
The coin landed on tails 6 out of 15 times.
The experimental probability of landing on tails was 6/15, which reduces to 2/5
The expression written in equivalent form with a common denominator is -1/6
<h3>Adding fractions</h3>
Fractions are written as ratio of two integers. For instance a/b is a fraction.
Given the sum of the fractions shown;
-3/4 and 5/8
Sum = -3/4 + 5/8
Sum = 5/8 - 3/4
Sum = 5-6/8
Sum = -1/8
Hence the sum of the given fraction -1/3 and 5/8 is -1/6

You can add the two equations together, this way you get:
5x = 25
You divide by 5:
x = 5
Now you just have to use this number in one of the original equations to get y:
x - 7y = -16
5 - 7y = -16 /subtract 5
-7y = -21 /divide by 7
-y = -3 /multiply with -1
y = 3
