Step-by-step explanation:
2/3 = (8/x) + 6
-6 -6
2/3 - 6 = -16/3

x = 40/3
The price of less expensive equipment is $1575.
Step-by-step explanation:
Let,
Price of one equipment = x
Price of other equipment = y
According to given statement;
x+y=4000 Eqn 1
x = y+850 Eqn 2
Putting Eqn 2 in Eqn 1

Dividing both sides by 2;

Putting y=1575 in Eqn 2;

The price of less expensive equipment is $1575.
