Answer 2

Answer:

$3(2x - 3) = 4(2x + 4)$

$6x - 9 = 8x + 16$

$6x - 8x = 9 + 16$

$- 2x = 25$

$x = \frac{25}{ - 2}$

$x = \frac{ - 25}{2}$

By putting the value of x

$3 \times ((2 \times \frac{ - 25}{2} ) - 3) = 4((2 \times \frac{ - 25}{2}) + 4)$

$3 \times ( - 25 - 3) = 4 \times ( - 25 + 4)$

$3 \times ( - 28) = 4 \times ( - 21)$

$- 84 = - 84$

Therefore LHS = RHS

hence the value is x is -25/2
