16-4c=20

-4c = 4

c = -1

To solve the equation 16 - 4c = 20, we can follow these steps:

Step 1: Begin by isolating the variable term on one side of the equation. In this case, we have the term -4c. To move it to the other side, we need to add 4c to both sides of the equation.

16 - 4c + 4c = 20 + 4c

Simplifying, we get:

16 = 20 + 4c

Step 2: Next, we want to isolate the c term. To do this, we can subtract 20 from both sides of the equation.

16 - 20 = 20 + 4c - 20

Simplifying, we get:

-4 = 4c

Step 3: Finally, divide both sides of the equation by 4 to solve for c.

-4/4 = 4c/4

Simplifying, we get:

-1 = c

So, the value of c in the equation 16 - 4c = 20 is -1.

To solve the equation 16 - 4c = 20, we need to isolate the variable "c" on one side of the equation.

Step 1: Start by subtracting 16 from both sides of the equation:
16 - 16 - 4c = 20 - 16
-4c = 4

Step 2: Divide both sides by -4 to solve for "c":
-4c / -4 = 4 / -4
c = -1

Therefore, the solution to the equation 16 - 4c = 20 is c = -1.
