Linear algebraic augmented matrix for solving equations

Discuss according to the situation
Let the rank of coefficient matrix be r (a) and the rank of augmented matrix be r (b)
When R (a) = R (b) = 3, i.e. - K ^ 2 + K + 2 is not equal to 0, i.e., K ≠ 2 and K ≠ - 1, the equations have unique solutions
When k = 2, R (a) = 2, R (b) = 3, there is no solution
When k = - 1, R (a) = R (b) = 2, the equations have infinite solutions

Party A and Party B process 360 parts respectively. Party A takes 4 hours to complete, and Party B takes 3.6 hours to complete. What is the ratio of working time between Party A and Party B? What is the formula

What is the working time ratio of Party A and Party B
4:3.6=10:9
What's the efficiency ratio between a and B
1/4:1/3.6=9:10

What is the correct solution to the equation: 1 / 2 x-3 X-5 = 1?
A：3X-2X+10=1
B：3X-2X-10=1
C：3X-2X-10=6
D：3X-2X+10=6

x/2-(x-5)/3=1
3x-2x+10=6
The correct solution to the equation is d

The total number of warehouses A and B is 80 tons. One third of warehouse A is equal to one fourth of warehouse B. how many tons of grain are stored in each warehouse?

Suppose a x tons B 80-x tons
Because one third of warehouse A is equal to one fourth of warehouse B
Then x / 3 = (80-x) / 4
The solution is x = 240 / 7
80-x=320/7
So a 240 / 7 tons, B 320 / 7 tons
