Solve for an and d. 1/4=a+8d

To solve for a and d in the equation 1/4 = a + 8d, we need to isolate each variable.

1. Start by isolating a:
1/4 = a + 8d
Subtract 8d from both sides:
1/4 - 8d = a
a = 1/4 - 8d

2. Next, isolate d:
1/4 = a + 8d
Substitute the value of a from step 1:
1/4 = 1/4 - 8d + 8d
1/4 = 1/4
0 = 0

Since the equation 0 = 0 is always true, there are infinitely many solutions for d. Therefore, d can take on any value and a can be calculated using the formula a = 1/4 - 8d.
