To determine Rajah's hourly wage, two equations can be set up based on his earnings. Let x represent his hourly wage and y represent the tips earned. The first equation from the first week is 12x + y = 117, and the second equation from the second week is 10x + y = 110. By solving these equations simultaneously, one can find the values of x and y, ultimately revealing Rajah's hourly wage. The discussion emphasizes the importance of forming and solving linear equations to tackle real-world problems.

Rajah earns an hourly wage plus tips. One week he worked 12 h and made a total of \$117. The next week he worked 10 h and earned the same amount in tips as the week before, for a total of \$110. What is Rajah's hourly wage?

I need help getting the two equations

Thread 'Erroneously finding discrepancy in transpose rule'

Obviously, there is something elementary I am missing here. To form the transpose of a matrix, one exchanges rows and columns, so the transpose of a scalar, considered as (or isomorphic to) a one-entry matrix, should stay the same, including if the scalar is a complex number. On the other hand, in the isomorphism between the complex plane and the real plane, a complex number a+bi corresponds to a matrix in the real plane; taking the transpose we get which then corresponds to a-bi...
