4C =2A + 2B , 2B = A + 3C How many C's will balance the combination of A and B

4C = 2A + 2B ----> C = (2A+2B)/4

2B = A+3C ------> C = (2B-A)/3

(2A + 2B)/4 = (2B-A)/3
6A + 6B = 8B - 4A
10A = 2B
B = 5A

into C = (2A+2B)/4
C = (2A + 10A)/4
C = 3A

etc

Solve the set of linear equations by the matrix method : a+3b+2c=3 , 2a-b-3c= -8, 5a+2b+c=9. Sove for c

To determine how many C's will balance the combination of A and B, we need to solve the given equations.

Let's start by substituting the value of 2B from the second equation into the first equation:

4C = 2A + (A + 3C)

Simplify the equation:

4C = 2A + A + 3C

Combine like terms:

4C - 3C = 2A + A

C = 3A

Now we have an expression for C in terms of A. To balance the combination of A and B, we need C to be equal to the sum of A and B.

C = A + B

Substitute the value of C we found earlier:

3A = A + B

Subtract A from both sides:

3A - A = B

2A = B

So, to balance the combination of A and B, the number of Cs should be twice the number of As.
