The equation we can use is

3 + 1/4c = 9

To find the total number of pieces, we would just solve the equation.

3 + 1/4c = 9

3 - 3 +1/4c = 9 - 3

1/4c = 6

inverse of division is multiputcation

4/1 *1/4c = 6*4

c = 24

There were 24 pieces of cake in total.

-11y = 6(2+1) - 13y
iris [78.8K]

Answer:

12

Step-by-step explanation:

Let's put the equations in standard form. For the first equation, we have:

−11y=6(z+1)-13y

2y−6z=6

y−3z=3

The second equation is:

4y−24=c(z−1)

4y−cz=24−c

If we multiply the first equation by 4, we get:

4y-12z=12

Comparing the two equations, we see that if c=12, both equations will be the same and there will be infinitely many solutions.

The correct value of c is 12.
