Question

10.5x+9 = 5 +3x then x =​

Answer 1

Answer:

$10.5x + 9 = 5 + 3x$

$10.5x - 3x = 5 - 9$

$7.5x = - 4$

$x = \frac{ - 4}{7.5}$

$x = -0.53$

Answer 2

5x + 9 = 5 + 3x

=> 5x - 3x = 5 - 9

=> 2x = - 4

=> x = - 4 / 2

=> x = - 2

=> 5x + 9 = 5 + 3x

=> 5( - 2 ) + 9 = 5 + 3( - 2 )

=> -10 + 9 = 5 - 6

=> - 1 = - 1
