Question

2 Start with number x. triple it and thin subtract 7, if the result is x +11, find the value of A.5 B.6 C.8 D. 9​

Answer 1

Here’s your answer:

Given:
take a number ‘x’

‘Triple it’ means add it 3 times

So, x + x + x = 3x

Subtract it with 7

3x - 7

Result is x + 11

Therefore, 3x - 7 = x + 11

Rearrange the terms and solve the equation

3x - x = 11 + 7

2x = 18

x = 18/2

x = 9

so answer is d) 9
