Найдите корень уравнения; 1) ⅓ x+6=2x 2) ½(4x-2)= -7 3) ⅚ x+3=⅙ x

1) 1/3Х + 6 = 2Х; 5/3Х = 6; Х = 6 : 5/3; Х = 18/5; Х = 3 3/5... 2) 1/2( 4Х - 2) = -7; 2Х - 1 = -7; 2Х = -7 + 1; 2Х = -6; Х = -6 : 2; Х = -3 3) 5/6Х + 3 = 1/6Х; 5/6Х - 1/6Х = -3; 4/6Х = -3; 2/3Х = -3; Х = -3 : 2/3; Х = - 9/2; Х = - 4 1/2.
