Question

16= -5+z/4 a. 69 b. -1 c. 9 d. 59

Answer 1

$16 = \frac{-5+z}{4}$

Multiply both sides by 4

$16\times 4 = \frac{-5+z}{4} \times 4$

$64 = -5+z$

Rearrange the terms

$64 = z - 5$

Add 5 on both sides.

$64 + 5 = z - 5 + 5$

$\boxed{\bf{z = 69}}$


Your final answer is a. 69.

Answer 2

If you would like to solve the equation 16 = (- 5 + z) / 4, you can do this using the following steps:

16 = (- 5 + z) / 4       /*4
16 * 4 = - 5 + z
16 * 4 + 5 = z
 z = 69

The correct result would be a. 69.
