124y3y=8 12y=8 y=128 y=4 #3 3xy=1 x=2y5 sol let, 3xy=1 eq(i) x=2y5 eq(ii) substitute the value of x from eq(ii) in eq(i), then eq(i)will be 3(2y5)y=1 6y15y=1 7y15=1 7y=115 7y=14 y=2 #4 xy=6 y=32x sol let, xy=6 eq(i) y=32x eq(ii) substitute the value of y from eq(ii) in eq(i) then eq(i) will be x(32x)=6 x32x=6 3 Exercise 51 Solve the following systems of simultaneous linear equations by the substitution method (1 to 4) 1 (i) x y = 14 x – y = 4 (ii) s – t = 3Solution for 5 (x 3) (5y 2) = 14 and 2x 3y = 4 6 x yz 124 and x y z= 112 (x y) (y 2) 2 = 5 21 and 2x y 3x = 8 7 8 W X yz Q Find the first, second, and the third derivatives of the following functions f(x) = (x* 4) 4x A Note As per our company guidelines we are supposed to answer the first three subparts of the quest
Solve by Substitution 2x3y=1 y=x1 Replace all occurrences of with in each equation Tap for more steps Replace all occurrences of in with Simplify Tap for more steps Simplify each term Tap for more steps Apply the distributive property Multiply by Subtract fromAnswer (1 of 5) 3x 9y = 3 (1) Divide both sides by 3, you get x 3y = 1 (1) 2x 6y = 2 (2) Divide both sides by 2, you get x 3y = 1 (2) You can see that (1) and (2) represent the same equation of a line, and for any real value of x, there is one and only one real value of y su1 xy=0 2xy=3 The system is consistent The point of intersection is (1, 1) Checking x=1, y=1 11=0 211=3 2 x2y=1,x3y=0 The system is consistent, but the point of intersection can only be estimated This example points out the main weakness in solving a system graphically
