Question

slove the following equations without transposing and check result 3(x-3)=5(2x+1) and checking process​

Answer 1

Answer:

Step-by-step explanation:

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

3x - 9 = 10x + 5

3x - 10x = 5 + 9

- 7x = 14

x = - 14 / 7

x = - 2

Checking : -

x = - 2

LHS : -

3 ( x - 3 )

= 3 ( - 2 - 3 )

= 3 ( - 5 )

= - 15

RHS : -

5 ( 2x + 1 )

= 5 ( 2 ( - 2 ) + 1 )

= 5 ( - 4 + 1 )

= 5 ( - 3 )

= - 15
