Answer 1

78+(84-р)-13=92;                                                                                            78+84-р-13=92;                                                                                              р=92+13-84-78;                                                                                              р=-57

Answer 2

84-р=92-78+13;
84-р=27;
-р=27-84;
р=57.

Answer 3

To solve the equation, we need to simplify the left-hand side first by performing the operations inside the parentheses:

78 + (84 - p) - 13 = 92

We can simplify the expression inside the parentheses by subtracting p from 84:

78 + 84 - p - 13 = 92

Combining like terms, we get:

149 - p = 92

To solve for p, we can isolate it by subtracting 149 from both sides:

• p = 92 - 149

Simplifying, we get:

p = -57

Therefore, the solution to the equation is p = -57.
