Question

Solve for d. 41 = 12 d _ 7 d

Answer 1

Answer:

$d=4$

Step-by-step explanation:

$41=12d-7$

In this scenario we need to isolate the variable.

Start by adding 7 to both sides:

$41+7=12d-7+7$

$48=12d$

Divide both sides by 12:

$\frac{48}{12}=\frac{12d}{12}$

$d=4$

Substitute 4 for d to check our answer:

$41=12d-7\\41=12(4)-7\\41=48-7\\41=41\rightarrow\text{correct!}$

Therefore the answer is:

$d=4$
