Question

. Подберите корень уравнения:
1) x+(-2) = 7; 2) -6 +y= 3;
4) 4 + m = 2;
5) x+(-4) = 8;
7) m +1 = -2; 8) 9 + y = 4;
3) x+ 2 = -3;
6) -2 + m = 1;
9) y + (-7) = 10.​

Answer 1

Ответ:

$1)x + ( - 2) = 7 \\ x - 2 = 7 \\ x = 9$

$2)y = 9 \\ 4)m = - 2 \\ 5)x = 12$

$7)m = - 3 \\ 8)y = - 5$

$3)x = - 5 \\ 6)m = 3 \\ 9)y = 17$
