• ### How can one straight line have two equations?

y = -2/3 x + 4

Multiply both sides by -3:
-3y = 2x - 12

Rearrange:
2x + 3y = 12

Both equations are the same, just written differently.
y = -2/3 x + 4

Multiply both sides by -3:
-3y = 2x - 12

Rearrange:
2x + 3y = 12

• ### Ship From Shore Distance?

Best answer: Draw a diagram - circle with radius r construct tangent - right angle triangle from 6ft observer to horizon calculate length of tangent using pythagoras. Note as 6 is so small compared to radius of earth you can ignore it and simplify to Distance in feet β sqrt ( 2 x 3960 x 5280 x 6 ) = 15840 feet or 3 miles. show more

• ### How to solve this simultaneous equation with steps?

Best answer: Multiply 1st equation by 2:
10x + 24y = 122.
Now subtract the 2nd equation, obtaining:
0x + 11y = 33.
Therefore y = 3.
Plug that into the 1st equation and you get
5x = 25, so x = 5.
