Question

12( x+5) = 4 (2x+9) + 4x

Answer 1

12( x+5 ) = 4 ( 2x+9 ) + 4x

( 12x + 12×5 ) = ( 4×2x + 4×9 ) + 4x

12x + 60 = 4×2x + 36 + 4x

60 = 4×2x + 36 + 4x - 12x

60 - 36 = 4×2x - 8x

24 = 4×-6x

24÷4 = -6x

6 = -6x

x = 6÷-6

x = -1

Answer 2

x=0

Explanation:

12x+60=8x+36+4x

12x+60=12x+36

60=36

x=0
