Solve 3x Y 14 X Y 2 Brainly In
Substituting the value of y in equation (iii) =4(2x−3 7)3x−19=0 =8x−1221x−133=0 =29x=145 =x=5 Putting the value of x in the above equation =y=1 The value of x and y are 5 and 1 respectively Suggest correctionsXY=14 and xy=9 then xy= to solve the above problem we need to learn basic formulas like 1) (ab)^2= a^2b^22ab and 2) (ab)^2=a^2b^22ab now apply the above formulas to given data by squaring both sides for xy=9 ==> (xy)^2=9^2 ==> x^2y^22xy=81, now assign given assign

Given=> x y = 14 equation 1 x y = 4 equation 2 Now, we will solve it by substitution method;Subject to the constraint 2x2 (y 1)2 18 Solution We check for the critical points in the interior f x = 2x;f y = 2(y1) =)(0;Finite Math Solve for y 2xy=14 2x y = 14 2 x y = 14 Subtract 2x 2 x from both sides of the equation y = 14− 2x y = 14 2 x
SOLUTION 1 Begin with x 3 y 3 = 4 Differentiate both sides of the equation, getting D ( x 3 y 3) = D ( 4 ) , D ( x 3) D ( y 3) = D ( 4 ) , (Remember to use the chain rule on D ( y 3) ) 3x 2 3y 2 y' = 0 , so that (Now solve for y' ) 3y 2 y' = 3x 2, and Click HERE to return to the list of problems SOLUTION 2 Begin with (xy) 2 = x y 1 Differentiate both sidesExtended Keyboard Examples Upload Random Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals For math, science, nutrition, history, geography, engineering, mathematics, linguistics, sports, finance, musicSee the answer See the answer See the answer done loading Show transcribed image text Expert Answer Who are the experts?

Change one of the equations to its opposite, add and solve for x 4x 2y = 14 4(2) 2y = 14 8 2y = 14 2y = 6 y = 3 Substitute x = 2 into one of the original equations and solve for y Answer The solution is (2, 3) Go ahead and check this last example—substitute (2, 3) into both equations You get two true statements 14 = 14 and 16As, the given equation is x y = 14 and x − y = 4 Now, write the first equation in for y in the terms of x So, x y = 14 can be written as y = 14 − x Now, use the above value of y in the second given equation x − y = 4 x − ( 14 − x) = 4 x − 14 x = 4 2 x − 14 = 4 2 x = 4 14 2 x = 18 x = 18 2 x = 9
