Question

памогите

решить уравнения:
1) 8a + 10 = 3a - 10;
2) 10(x - 2) – 12 = 14(x - 2);
3) -25(-8y + 6) = -750;
4) -10(-4x – 10 - 24) = 300;
5) -10a + 128 = -74a;
6) 3(5y - 6) = 16y - 8;
7) -5(3z +1) – 11 = -1;
8) -8n + 4 = -2(5n + 6);
9) 20 + 30k = 20 + k;
10) 26 – 5m = 2 – 9m;​

Answer 1

6.
3(5y-6)=16y-8
15y-24=16y-8
15y-16y=-8+24
Y=16


7. -5(3z+1)-11=-1
-15z-5-11=-1
-15z=5+11-1
-15z=15 (*-1)
15z=-15
Z=-15:15
Z=-1
