Решить линейные уравнения, буду вам. решение полное. 4 - 3x = -7x - 4 7x = 5 + 2(6x - 5) 9 + 5(4x - 3) = 7x - 6 25 - (3x + 5) = 7(4x + 3) 6(2x + 7) - 2(6x - 5) = 3x - 2 11(x - 2) - (2x - 3) = 9(x + 2)

1) 4-3х=-7х-4                    3)9+5(4х-3)=7х-6
-3х+7х=-4-4                      9+20х-15=7х-6
4х=-8                                20х-7х=-6-9+15
х=-8:4                               13х=0
х=-2                                  х=0
2) 7х=5+2(6х-5)                4) 25-(3х+5)=7(4х+3)
7х=5+12х-10                     25-3х-5=28х+21
7х-12х=5-10                      -3х-28х=21-25+5
-5х=-5                                -31х=1
х=-5:-5                              х=-
х=1
5) 6(2х+7)-2(6х-5)=3х-2   6)11(х-2)-(2х-3)=9(х+2)
12х+42-12х+10=3х-2          11х-22-2х+3=9х+18
12х-12х-3х=-2-42-10           11х-2х-9х=18+22-3
-3х=-54                                 0х=37
х=-54:(-3)                              х - любое число
х=18
