Question

Solve the following equations and check you results

3 (x - 3)=5 (2x + 1)​

Answer 1

Answer:

3(x-3)=5(2x+1)

3x-9=10x+5

3x-10x =5+9

-7x=14

-×=14/7

(x=-2 )

Answer 2

Answer:-

3x - 9 = 10x + 5

=> 3x - 10x = 5 + 9

=> -7x = 14

=> x = -14/7       ( 14/-7 = -14/7 )

=> x = -2 -------> is the answer

Result check:-

substituting x = -2 in given equation ;

3 ( -2 - 3 ) = 5 ( 2(-2) + 1 )

=> 3 ( -5 ) = 5 ( -4 + 1 )

=> -15 = 5 ( -3 )

=> -15 = -15
