Question

Solve for z. - z/2 + 35= 42

Answer 1

Answer:

z = 49. first, multiply both sides by 2. (-z/2 x 2 = -z, 42 x 2 = 84) next, subtract 35 from both sides. (35 - 35 = 0, 84 - 35 = 49) finally, change the negative variable (-z) to a positive variable (z) and 49 becomes negative. z = -49. hope this helps

Step-by-step explanation:

Answer 2

Answer:

z = -14

Step-by-step explanation:

$- \frac{z}{2} + 35 = 42$

$- z + 70 = 84$

$- z = 84 - 70$

$- z = 14$

$\boxed{\green{z = - 14}}$
