Prosze pomóżcie ja tego nie rozumniem. 1. Rozwiąż równania. a) 1/3x - 2= x+2 b) 1-6/7x=4/7 c) 6(1/4x-2) = 18 d)x/6-1/6=1 e)-2(2x-1) = x/3 f) 2/5 (3-x) = -2 g)3/4(2-3x) = -6 h)1/5(x-3)m = 9-x

a) 1/3x - 2= x+2 1/3x - x = 2 + 2 -2/3x = 4 / * (-3/2) x = -6 b) 1-6/7x=4/7 - 6/7x = 4/7 - 1 - 6/7x = -3/7 / * ( -7/6) x = 1/2 c) 6(1/4x-2) = 18 3/2x - 12 = 18 3/2x = 18 + 12 3/2x = 30 / * 2/3 x = 20 d)x/6-1/6=1 x/6 = 1 + 1/6 1/6x = 1 + 1/6 / * 6 x = 6 ( 1 + 1/6 ) x = 6 + 1 x = 7 e)-2(2x-1) = x/3 -4x + 2 = 1/3x -4x + 1/3x = -2 -3 i 2/3x = -2 -11/3x = -2 / * ( - 3/11 ) x = 6/11 f) 2/5 (3-x) = -2 6/5 - 2/5x = -2 -2/5x = -2 - 6/5 -2/5x = -3 i 1/5 -2/5x = - 16/5 / * ( - 5/2 ) x = 8 g)3/4(2-3x) = -6 3/2 - 9/4x = -6 -9/4x = -6 - 3/2 -9/4x = -7 i 1/2 -9/4x = -15/2 / * ( - 4/9 ) x = 10/3 h)1/5(x-3) = 9-x 1/5x - 3/5 = 9 - x 1/5x + x = 9 + 3/5 6/5x = 9 i 3/5 6/5x = 48/5 / * 5/6 x = 8 pozdrawiam :)

Całość daję w załączniku :))
