-3j - -4
------------------ = 12
-6
Multiply each side by -6 to clear the fraction
-3j +4
------------------ * -6 = 12 *-6
-6
-3j +4 = -72
Subtract 4 from each side
-3j +4-4 = -72 -4
-3j = -76
Divide each side by -3
-3j/-3 = -76/-3

Answer:
x=10
Step-by-step explanation:
Let x be the number of $5 items sold.
Let y be the number of $25 items sold.
x + y = 150
x = 150 - y .........(1)
5x + 25y = 1950 ......(2)
Plugging the expression for x from (1) into (2), we get:
5(150 - y) + 25y = 1950
750 - 5y + 25y = 1950
20y = 1200
y = 60 items.
The answer is, there were 60 items sold at $25.
