Решить уравнение 1) 4y+7=5y+4 2) -9x-56=5x 3) 35-11m=3m+21 4) -12z+95=-7z 5) 7n+12=6n+8

1) 4y + 7 = 5y + 4

4y - 5y = 4 - 7

-y = -3

y = 3

2) -9x - 56 = 5x

-9x - 5x = 56

-14x = 56

x = 56 ÷ (-14)

x = -4

3) 35 - 11m = 3m + 21

-11m - 3m = 21 - 35

-14m = -14

m = -14 ÷ (-14)

m = 1

4) -12z + 95 = -7z

-12z + 7z = -95

-5z = -95

z = -95 ÷ (-5)

z = 19

5) 7n + 12 = 6n + 8

7n - 6n = 8 - 12

n = -4
