Solve -5b + 3b = -9b - 4z + 6 for b in terms of z.
| -1\(\frac{4}{13}\)z - \(\frac{1}{13}\) | |
| -\(\frac{3}{4}\)z - \(\frac{5}{12}\) | |
| -1\(\frac{3}{4}\)z + 1\(\frac{1}{2}\) | |
| -z + 1 |
To solve this equation, isolate the variable for which you are solving (b) on one side of the equation and put everything else on the other side.
-5b + 3z = -9b - 4z + 6
-5b = -9b - 4z + 6 - 3z
-5b + 9b = -4z + 6 - 3z
4b = -7z + 6
b = \( \frac{-7z + 6}{4} \)
b = \( \frac{-7z}{4} \) + \( \frac{6}{4} \)
b = -1\(\frac{3}{4}\)z + 1\(\frac{1}{2}\)

If the length of AB equals the length of BD, point B __________ this line segment.
trisects |
|
midpoints |
|
bisects |
