The solution equation is: 1) X-1 of 2x-1 + 5x-8 of 1-2x = - 3 (2) 3-x of 1-x - 7-x of 5-x = 1 - X & # 178; - 8x + 7 of 7 x²-2 | Math enthusiast | Mathematical art

The solution equation is: 1) X-1 of 2x-1 + 5x-8 of 1-2x = - 3 (2) 3-x of 1-x - 7-x of 5-x = 1 - X & # 178; - 8x + 7 of 7 x²-2

1) 2x-1: X-1 + 1-2x: 5x-8 = - 3 (x-1) / (2x-1) - (5x-8) / (2x-1) = - 3x-1-5x + 8 = - 6x + 32x = - 4x = - 2. The test shows that x = - 2 is the solution of the equation. The solution of the equation is x = - 2 (2) 1-x: 3-x - 7-x: 5-x = 1 - X & # 178; - 8x + 7: X & # 178; - 2 (x-3) / (x-1) - (X-5)
