Пожалуйста срочно помогите решить уравнения. 1)7-3x=x+11 2)2(x+3)=x+13 3)4(5-x)=3x-1 ;4)3(x-2)=x+4 ; 5)5(x-1)=4x+3

1) 7 - 3x = x + 11 -3х - х = 11 - 7-4х = 4х = -1проверка:7 - 3 ( -1) = -1 + 117 + 3 = 1010 = 102) 2 ( x + 3 ) = x + 13 2х + 6 = х + 132х - х = 13 - 6х = 7проверка:2 ( 7 + 3 ) = 7 + 132 * 10 = 2020 = 203) 4 ( 5 - x ) = 3x - 1 20 - 4х = 3х - 1-4х - 3х = - 1 -20-7х = -217х = 21 х = 21 : 7х = 3проверка: 4 ( 5 - 3 ) = 3 * 3 - 14 * 2 = 9 - 18 = 84) 3 ( x - 2 ) = x + 4 3х - 6 = х + 43х - х = 4 + 62х = 10х = 10 : 2х = 5проверка:3 ( 5 - 2 ) = 5 + 4 3 * 3 = 99 = 95) 5 ( x - 1 ) = 4x + 35х - 5 = 4х + 35х - 4х = 3 + 5х = 8проверка: 5 ( 8 - 1 ) = 4 * 8 + 35 * 7 = 32 + 335 = 35
