Решите уравнение:1)15х-9=7+11х ; 2)-4-3х=2х-49 ; 3)7+3х=26+2х ; 4)5х-3(х+2)=5х-6 ; 5)6х-19=5х+1

1) 15х - 9 = 7 + 11х 15 х - 11х = 7 + 9 4х = 16 х = 16 : 4 = 4 2) -4 - 3х = 2х - 49 -4 + 49 = 2х + 3х 5х = 45 х = 45 : 5 = 9 3) 7 + 3х = 26 + 2х 3х - 2х = 26 - 7 х = 19 4) 5х - 3(х + 2) = 5х - 6 5х - 3х - 6 = 5х - 6 5х - 3х - 5х = - 6 - 6 -3х = -12  х = 12 : 3 = 4 5) 6х - 19 = 5х + 1 6х - 5х = 1 + 19 х = 20
