Substitute y = 2x - 15 to the second equation:

4x + 3(2x - 15) = -5 use distributive property

4x + (3)(2x) + (3)(-15) = -5

4x + 6x - 45 = -5 add 45 to both sides

10x = 40 divide both sides by 10

x = 4

Substitute the value of x to the equation y = 2x - 15:

y = 2(4) - 15 = 8 - 15 = -7

<h3>Answer: (4, -7)</h3>
