$d = - 11.6$ $d = -11.6$

$- 11.9 d - 19.86 = 19.12 + 14.48 - 7.3 d$ $-11.9 d -19.86 = 19.12 + 14.48 - 7.3 d$

Collect the like terms

$- 11.9 d + 7.3 d = 19.86 + 19 .12 + 14.48$ $-11.9 d + 7.3 d = 19.86 + 19 .12 +14.48$

$- 4.6 d = 53.36$ $-4.6 d = 53.36$

Divide through by $- 4.6$ $-4.6$

$d = - 11.6$ $d = -11.6$

How do you solve −11.9d−19.86=19.12+14.38−7.3d-11.9d - 19.86= 19.12+ 14.38- 7.3d?
