Question

solve for d.\
-16 + 7d - 4 = 6(d - 5) - 9\
d = \boxed{}

Explanation:

Step1: Simplify both sides

Left side: \(-16 - 4 + 7d = -20 + 7d\)
Right side: \(6d - 30 - 9 = 6d - 39\)
So the equation becomes \(-20 + 7d = 6d - 39\)

Step2: Subtract \(6d\) from both sides

\(-20 + 7d - 6d = 6d - 39 - 6d\)
Simplify: \(-20 + d = -39\)

Step3: Add 20 to both sides

\(-20 + d + 20 = -39 + 20\)
Simplify: \(d = -19\)

Answer:

\(d = -19\)
