What is the first step to solve the equation:
11 - 3x = 44

11-3x=44  

One solution was found :

                  x = -11

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    11-3*x-(44)=0  

Step by step solution :

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  -33 - 3x  =   -3 • (x + 11)  

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    -3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    x+11 = 0  

Subtract  11  from both sides of the equation :  

                     x = -11

One solution was found :

                  x = -11

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.
