4x - 3y = 8 ⇒ 8x - 6y = 16
5x - 2y = -11 ⇒ 15x - 6y = -33
-7x = 49
-7 -7
x = -7
4x - 3y = 8
4(-7) - 3y = 8
-28 - 3y = 8
+ 28 + 28
-3y = 36
-3 -3
y = -12
(x, y) = (-7, -12)
To use elimination you have to multiply the first graph by 2 and the second graph by 3 so that the two y-axis can be equal to -6. Then you do the rest to find the answer of the x-axis and the y-axis.

Step-by-step explanation:
6t-10is the awsner. If s is the number of nautical miles separating the ships, express s in terms of t(the number of hours after 12 noon). I formed the equation s squared to the second power equals (12t) squard to the second power + (10 - 16) squared to the second power
