Question

Solve for z
-p(d+z) = -2z+59−p(d+z)=−2z+59

Answer 1

z=-59+pd/-p+2

Explanation:

Got it right on Khan

Answer 2

`-p(d+z)=-2z+59\qquad\text{use distributive property}\\\\-pd-pz=-2z+59\qquad\text{add pd to both sides}\\\\-pz=-2z+pd+59\qquad\text{add 2z to both sides}\\\\2z-pz=pd+59\\\\z(2-p)=pd+59\qquad\text{divide both sides by}\ (2-p)\\eq0\\\\\boxed{z=(pd+59)/(2-p)}`
