6 more than thrice a number and then subtracting 5 gives us 25. The number is

A
6

B
8

C
10

D
12

Solution

Let the number be x
3x + 6 – 5 = 25
3x + 1 = 25
3x = 24
x = 8
Question 2
1 / -0

What is the value of x that makes the following expression true?

x + {5 - (-3 - (7 × 2 - 6)} = 15

A
-15

B
-10

C
-1

D
10

Solution

x + {5 - (-3 - (7 × 2 - 6)} = 15
x + {5 - (-3 - (8)} = 15
x + {5 - (-11)} = 15
x + {5 + 11} = 15
x + {16} = 15
x = 15 - 16
x = -1
