Решите линейные уравнения: 1) 6x+18-0 2) 2x+5=0 3)2x-10=-3 4)-5x-1=0 5)-5x+6=0 6)9x+6=10x

1)6x+18=0 6x=-18 x=-3 2)2x+5=0 2x=-5 x=-2,5 3)2x-10=-3 2x=-3+10 2x=7 x=3,5 4)-5x-1=0 -5x=1 x=-0,2 5)-5x+6=0 -5x=-6 x=1,2 6)9x+6=10x 9x-10x=-6 -x=-6 x=6

1) 6x + 18 = 0 6x = -18 [latex]x=- \frac{18}{6} =-3[/latex] 2) 2x + 5 = 0 2x = -5 [latex]x=- \frac{5}{2} =-2 \frac{1}{2} =-2,5[/latex] 3) 2x - 10 = -3 2x = -3 + 10 2x = 7 [latex]x= \frac{7}{2} =3 \frac{1}{2} =3,5[/latex] 4) -5x - 1 = 0 -5x = 1 [latex]x= \frac{1}{-5} =-0,2[/latex] 5) -5x + 6 = 0 -5x = -6 5x = 6 [latex]x= \frac{6}{5} =1 \frac{1}{5} =1,2[/latex] 6) 9x + 6 = 10x 6 = 10x - 9x 6 = x
