Given the equation:
25d - 16 = 4d + 26
Determine the value of d.
Solution:
In order to determine the value of, we simply need to transpose first 4d and -16 on the opposite side of the equations, hence it must be taken to note that in transposing a number, the sign changes.
25d - 16 = 4d + 26
25d - 4d = 26 + 16
21d = 42
Divide both sides by 21 in order to get the value of d.
21d/21 = 42/21
d = 2
Final answer:
d = 2
