Answer:
z = -b - 17 / ( a + 4 )
Step-by-step explanation:
az + 17 = -4z – b
collect like terms
az + 4z = -b -17
z( a + 4 ) = - b - 17
Divide both sides by ( a + 4 )
z = -b - 17 / ( a + 4 )
Divide the total portion (9 1/2 cups) by the portion size (3/4 cup).
=9 1/2 ÷ 3/4
convert 9 1/2 to improper fraction
=19/2 ÷ 3/4
to divide fractions, multiply by the reciprocal/inverse of 3/4
=19/2 * 4/3
multiply numerators; multiply denominators
=(19*4)/(2*3)
=76/6
=12.666666

Answer:
The general solution is

+ 
Step-by-step explanation:
Step :1:-
Given differential equation y(4) − 2y''' + y'' = e^x + 1
The differential operator form of the given differential equation
comparing f(D)y = e^ x+1
The auxiliary equation (A.E) f(m) = 0




The roots are m=0,0 and m =1,1
complementary function is 
<u>Step 2</u>:-
The particular equation is 
P.I = 
P.I = 
P.I = 



applying in integration u v formula

= 





again integration 
The general solution is 

+
