This picture should provide a full answer. What I did was rearrange the equation to get Tan(x) on one side, then in order to get rid of the Tan, I used Arctan, which got us the final answer.

Answer:the system of linear equations are
m + n = 54
3n + 8 + n = 54
Step-by-step explanation:
Let m represent the cost of the maths textbook.
Let n represent the cost of the novel.
Caral purchased a maths book and a novel that cost a total of $54 not including tax. It means that
m + n = 54 - - - - - - - - - - - - 1
If the price of the maths text book is $8 more than 3 times the price of the novel, it means that
m = 3n + 8 - - - - - - - - - -2
Substituting m = 3n + 8 into equation 1, it becomes
3n + 8 + n = 54
4n + 8 = 54
4n = 54 - 8 = 46
n = 46/4 = 11.5
m = 54 - n = 54 - 11.5
m = 42.5
Answer:
45.5
