Answer 2

Step-by-step explanation:

1)Let the number be y

2y + 8 = 20

Now , transposing 8 to the other side

2y = 20 - 8

2y = 12

Therefore y = 12/2

=6

So, the number Xavier thought of was 6.

2) Let the number be x

x/4 - 3= 2

Transposing 3 to the other side

x/4 = 2 + 3 = 5

x/4 = 5

Therefore, x = 5 × 4 = 20

The number Sasha thought of was 20

3) Let the number be z

5z + 10 = 7z

Transposing 5z to the other side

10 = 7z - 5z = 2z

10 = 2z

Therefore z = 10/2 = 5

The number Anders thought of was 5

4) Let the number be n

(n + 1) 3 = 4n - 4

3n + 3 = 4n - 4

Transposing

3 + 4 = 4n - 3n

n = 7

The number Ahmad thought of was 7

5) Let the number be m

(m - 6) 5 = (m - 5) 4

5m - 30 = 4m - 20

Transposing

5m - 4m = (-20) + 30

m = 10

The number Zalika thought of was 10
