Ответ:
1) -2q-5= -11
-2q = -11+5
q = -6/-2 =3
2) 3(8+k) = 33
24 + 3k = 33
3k = 33-24
K = 9/3 = 3
3) 4/6=x/9
By cross multiplication
4x9 = Xx6
36 = 6x
So, x = 6
4) 6(y+3)=24
6y + 18 = 24
y = (24-18)/6 = 1
5)4k+8=26
4k = 26-8
k = 18/4 = 4.50
6)8y=6+2y
8y - 2y = 6
6y = 6
So, y = 1
7)3x-7=20
3x = 20+7
x = 27/3 = 9

Would you be able to solve it that way ?
They're both the same number.
