Solution 1

Sure, let's solve the system of equations step by step.

We have two equations:

  1. 9x + 3y = -30
  2. -5x = y

Step 1: Solve the second equation for y:

y = -5x

Step 2: Substitute y in the first equation with -5x:

9x + 3(-5x) = -30 9x - 15x = -30 -6x = -30

Step 3: Solve for x:

x = -30 / -6 x = 5
