Solution 1

Sure, let's solve these equations step by step:

  1. First, let's rewrite the first equation to isolate y: y = 4x + 20

  2. Now, we can substitute y from the first equation into the second equation: x + (4x + 20) = 0

  3. Simplify the equation: 5x + 20 = 0

  4. Solve for x: x = -20/5 = -4
