Step-by-step explanation:
4x+92+2x+4=180
6x+96=180
6x=84
x=14
5y-13+8y+76=180
13y=117
/13
y=9
Answer:
They left the beach at 2:20pm

Answer:
a) 10x - 14y = -4
Step-by-step explanation:
Two equations linear dependent if you can write one as a multiple of the other. It means that the equation that is a linear dependent with -5x+7y=2 is:
10x - 14y = -4
Because it can be written as:
-2(-5x+7y) = -2(2)
So, this equation is equivalent to -5x + 7y = 2
