Problem 2: Judge if the following linear system of equations has solutions or not. If it has, find the solutions only by Gauss elimination. Note: there are many choices to make when using Gauss elimination. The choices I make when solving this lead to having fractional 3rds in one step, but you can get rid of them in the next step. So keep them in fraction form instead of decimal. 2x₁ + 5x2 + 4x3 + 5x4 = -5 2x₁ + 3x₂ + 3x3 - 1x4 = 7 2x13x2 + 3x3 + 4x4 = 3 2x1x2 + 5x3 - 4x4 21 =
