The solution equation: (1) 4x-3 (20-x) = - 4 (2) 3x − 14-1 = 5x − 76

The solution equation: (1) 4x-3 (20-x) = - 4 (2) 3x − 14-1 = 5x − 76

(1) Remove the bracket: 4x-60 + 3x = - 4, sort out: 7x = 56, the solution: x = 8; (2) remove the denominator: 3 (3x-1) - 12 = 2 (5x-7), remove the bracket: 9x-3-12 = 10x-14, shift term: 9x-10x = - 14 + 3 + 12, merge the similar term: - x = 1, divide both sides of the equation by - 1: x = - 1
