determinant method

determinant method : The climate is the weather averaged over a long period of time. See also: Earth & Climate Global Warming Climate Weather Environmental Issues Water Severe Weather Weather is the combination of events in the atmosphere and climate is the overall accumulated weather in a certain location. Over historic time spans there are a number of static variables that determine climate, including: latitude, altitude, proportion of land to water, and proximity to oceans and mountains. Other climate determinants are more dynamic: The thermohaline circulation of the ocean distributes heat energy between the equatorial and polar regions; other ocean currents do the same between land and water on a more regional scale. Degree of vegetation coverage affects solar heat absorption, water retention, and rainfall on a regional level. Alterations in the quantity of atmospheric greenhouse gases determines the amount of solar energy retained by the planet, leading to global warming or global cooling.

Question : How to solve this question? 5x-8y=3y-x+8=2x-y+1 I really have no idea why there's 3 equations in the question.How to solve simultaneous equations like this, as in how to change it to matrices? Can any experts out there clear my doubts?

Answer : Hi, Take 2 of 3 equations and simplify their equation. Repeat for a second pair of equations. 5x-8y=3y-x+8=2x-y+1 5x - 8y = 3y - x + 8 6x - 11y = 8 <=1st equation 3y - x + 8 = 2x - y + 1 -3x + 4y = -7 <=2nd equation Solve the system below by multiplying the second equation by 2. Then add the equations and solve. 6x - 11y = 8 -3x + 4y = -7 [8 . -11] [-7 . .4 ] = 8(4) - (-11)(-7) = 32 - 77 = -45 ------------ = -------------------- . ---------- . .----- = 5 = x [6 . -11] = 6(4) - (-11)(-3) = 24 - 33 = .-9 [-3 . .4 ] [6 . . 8] [-3 . -7] = . 6(-7) - (8)(-3) = -42 + 24 = -18 ------------ = -------------------- . ------------ . .----- = 2 = y [6 . -11] = 6(4) - (-11)(-3) = 24 - 33 = .-9 [-3 . .4 ] (5,2) <==ANSWER I hope that helps!! :-)..   More from Yahoo Answers
