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

z=(pd+59)/(2-p)

Step-by-step explanation:

-p(d+z)=-2z+59

Open bracket

-pd-pz=-2z+59

Collect like terms

2z-pz=pd+59

Factor out z

z(2-p)=pd+59

Divide both sides by (2-p)

z(2-p)/(2-p)=(pd+59)/(2-p)

z=(pd+59)/(2-p)

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
