i am having trouble finding out the right numbers for this one. need help. give me the right numbers. have a good day.

In the following set of equations, why can you NOT solve for a, b, c and d? 2a + 2b + 3c + 4d = 180 a+ b+ c+ d =60 3a + 3b + 2c + 4d = 180 6a + 6b + 9c + 12d = 460 O a. Two equations total 180. O b. The functions are not smooth and continuous. O C. Two equations are linearly dependent. O d. It is impossible to solve 4 x 4 matrixes. QUESTION 7 Find the inverse matrix (A71) for the following set of equations: P = 10 - 2Q P = 2+Q What is the number in R2, C2? O a. -1/3 O b. -2/3 O C. 1/3 O d. 2/3
