I'm not sure what you mean by 'written method' but the sum is 2,654.
Answer:
infinitely many solutions
Step-by-step explanation:
x + 6y = -5
3x + 18y = -15
Multiply the first equation by 3
3(x + 6y) = -5*3
3x + 18y = -15
The two equations are identical. This means they have infinite solutions along the line x+6y = -5
Your equation would look a lot like this
c(t) = 8.5t + $40

Step-by-step explanation:
The important rule to know is that when adding and subtracting matrices, first make sure the matrices have the same dimensions. In order words, you can add or subtract a 2x3 with a 2x3 or a 3x3 with a 3x3. However, you cannot add a 3x2 with a 2x3 or a 2x2 with a 3x3.
