Question

Solve for d.
2d + 4 = 10 + 2.5d
d=

Answer 1

To solve for d, subtract 2.5d from both sides, combine like terms, subtract 4 from both sides, and divide by -0.5.

Step-by-step explanation:

To solve for d in the equation 2d + 4 = 10 + 2.5d, we need to isolate the variable d. To do this, we can subtract 2.5d from both sides of the equation, which gives us:

2d - 2.5d + 4 = 10

Now, let's combine like terms:

-0.5d + 4 = 10

We can then subtract 4 from both sides:

-0.5d = 6

Finally, divide both sides of the equation by -0.5:

d = -12
