Решите уравнение: 1)4x=10; 2)1/2=–3; 3)x+18=0; 4)x–6=0; 5)5x–3=0; 6)7+6x=–4x–6; 7)7(x+2)=14; 8)5–2x=8x+9; 9)3x–10=2+6(5+4x); 10)7(–5+3x)+4x=9;

1)4х=20 Х=10/4=2,5 2)где икс? 3)х+18=0 Х=-18 4)х-6=0 х=6 5)5х-3=0 Х=3/5=0,6 6)7+6х=-4х-6 6х+4х=-6-7 10х=-13 Х=-1,3 7)7(Х+2)=14 7х+14=14 7х=0 Х=0 8)5-2х=8х+9 -2х-8х=9-5 -10х=4 Х=-(4/10)=-0,4 9)3х-10=2+6(5+4х) 3х-10=2+30+24х 3х-24х=32+10 -21х=42 Х=-(42/21)=-2 10)7(-5+3х)+4х=9 -35+21х+4х=9 25х=9+35 25х=44 Х=44/25=1,76

1) 4x = 10 x = 2,5 2) 1/2x = -3 x = -6 3) x+18 = 0 x = -18 4) x-6 = 0 x = 6 5) 5x - 3 = 0 5x = 3 x = 3/5 6) 7 + 6x = -4x - 6 6x + 4x = -6 -7 10x = -13 x = -1,3 7) 7(x+2) = 14 x+2 = 2 x = 0 8) 5-2x = 8x+9 -2x-8x = 9-5 -10x = 4 x = -4/10 9) 3x-10 = 2 + 6(5+4x) 3x-10 = 2 + 30 + 24x  3x - 24x = 32+10 -21x = 42 x = -2 10) 7(-5+3x) + 4x = 9 -35 + 21x +4x = 9 25x = 9+35 x = 44/25 = 1,76
