Question

solve the following equations by transpostition method
(a) 9(6 - X) - 36 = 9(6 + x)
(b)3(1+ y) + 7(3 + y) = Ily​

Answer 1

Step-by-step explanation:

Solution :-

a) Given equation is 9(6 - X) - 36 = 9(6 + x)

=> 54 - 9X -36 = 54 + 9X

(Removing brackets )

=> 18-9X = 54+9X

=> -9X-9X = 54-18

(Transposing 9X to LHS and 18 to RHS)

=> -18X = 36

=> X = 36/-18

(Transposing 18 to RHS )

=> X = -2

Therefore, The solution is -2

b)Given equation is 3(1+ y) + 7(3 + y) = 11y

=> 3+3y + 21+7y = 11y

(Removing brackets )

=> 10y+24 = 11y

=> 10y -11y = 24

(Transposing 11y to LHS)

=> -y = 24

=> y = -24

(multiplying with -1)

Therefore, y = -24

The solution is -24
