1/5+ 2/5 = 3/5
3/5 of his friends had arrived by 8.

-6 + 4x = 2 + 3x
Solve for x :))
Start by squaring both sides.
2sqrt(t-2) = sqrt(7-t)
sqrt(4t-8) = sqrt(7-t)
4t - 8 = 7 - t
5t = 15
t = 3
f(x) = 5
if x >= -4:
x = 3
else:
x = 2
Since x >= -4, x = 3.
f(3) = 5
f(y) = 3
if y >= -4:
y = sqrt(7)
y = 0
Since sqrt(7) >= -4, y = sqrt(7).
I think there's only one value that works, sqrt(7).
sine(x)*cot(x)
sine(x)*cos(x)/sine(x)
cos(x) = -2sqrt(2).
However, cos(x) must be in the range -1 to 1.
I think there aren't any answers.
Try adding 2 equations together, that will isolate one variable and give you the value for them.
(1+y)/(2-y) = 15
1 + y = 30 - 15y
16y = 29
y = 29/16
g(16) = sqrt(16) + 3 = 7
t(7) = 3 - g(7)
g(7) = sqrt(7) + 3
t(7) = 3 - (sqrt(7) + 3)
t(7) = -sqrt(7)
If we look at just last numbers, they sum up to a even number, meaning the number is divisable by 2.
Prime factor of 14 = 2 * 7
Prime factor of 424 = 2^3 * 53
So common factors are 2.
So either 1 or 2 are the possible numbers.
