6. Solve each equation algebraically. What are the restrictions on the variables?
a) 5x + 11 = x + 5
b) x + 3 = V2x - 7
c) V13 - 4x = 2 - x
d) x + V-2x + 9 = 3
7. Solve each equation algebraically and
graphically. Identify any restrictions on
the variables.
a) V8 - x = x + 6
b) 4 = x + 2x - 7

step-by-step explanation:

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.

3. solve the system of two equations:

$97520
