Question

solve for d.\
-5(-d + 5) - 7d = 13\
d = \boxed{}

Explanation:

Step1: Expand the left-hand side

$(-5)(-d) + (-5)(5) - 7d = 13$
$5d - 25 - 7d = 13$

Step2: Combine like terms

$(5d - 7d) - 25 = 13$
$-2d - 25 = 13$

Step3: Isolate the term with d

$-2d = 13 + 25$
$-2d = 38$

Step4: Solve for d

$d = \frac{38}{-2}$

Answer:

$d = -19$
