Answer:
-12x + 12 = 32............................. the equation
Step-by-step explanation:
to determine the equation in this 12(1-x) = 36 expression is quite simple, you only need to open the bracket .
solution
12(1-x) = 36
12 - 12x = 32
-12x + 12 = 32............................. the equation
we can further evaluate for the value of x
-12x = 32 - 12
-12x = 20
divide both sides by the coefficient of x which is -12
-12x = 20
-12x/-12 = 20/-12
x = -1.67

Answer:

Step-by-step explanation:
Represent Alice with A, her friend with F and you with Y.
From the question, we have:

--- Twice as much Alice means 2 times Alice's earnings
--- 2 less than her friend
Required
Determine the total amount

Substitute
for A in


Substitute
for F in 

The total amount is calculated by adding the earnings of Alice, her friend and you



<em>Hence, the total earnings is 5d - 2</em>
