Step-by-step explanation:

Step 1: Define Systems

-5x + 4y = 3

x = 2y - 15

Step 2: Solve for y

Substitution

Substitute in x [1st Equation]:                                                                           -5(2y - 15) + 4y = 3[Distributive Property] Distribute -5:                                                                -10y + 75 + 4y = 3Combine like terms:                                                                                         -6y + 75 = 3[Subtraction Property of Equality] Subtract 75 on both sides:                      -6y = -72[Division Property of Equality] Divide -6 on both sides:                                y = 12

Step 3: Solve for x

Substitute in y [2nd Equation]:                                                                        x = 2(12) - 15Multiply:                                                                                                             x = 24 - 15Subtract:                                                                                                            x = 9

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
