10=4-d2*5/7/2

To solve the equation, we can follow the order of operations (PEMDAS/BODMAS).

First, let's simplify the expression inside the parentheses:

10 = 4 - (d * 5 / (7 / 2))

Next, let's simplify the division inside the parentheses:

10 = 4 - (d * 5 / (3.5))

Now, let's multiply d by 5:

10 = 4 - (5d / 3.5)

Next, let's divide 5d by 3.5:

10 = 4 - (1.4286d)

We want to isolate the variable d, so let's move the constant term to the other side of the equation:

10 + 1.4286d = 4

Now, let's subtract 10 from both sides:

1.4286d = -6

Finally, let's divide both sides by 1.4286:

d = -6 / 1.4286

Calculating this division will give you the value of d.
