Question

Simplifying algebraic expression

Answer 1

4-6 = -2

x/7-6

Substitute

28/7-6

PEMDAS

28/7 = 4

4-6 = -2

(If you're looking for the expression, it's 4-6. But if straight answer, -2)

Answer 2

`\sf \: (x)/(7) - 6 = - 2`

Explanation:

Given information,

`\sf \rightarrow \: (x)/(7) - 6`

`\sf \rightarrow \: x = 28`

Now the value of expression is,

`\sf \rightarrow \: (x)/(7) - 6`

`\sf \rightarrow \: (28)/(7) - 6`

`\sf \rightarrow \: 4 - 6`

`\sf \rightarrow \: - 2 = > final \: value`

Therefore, the answer is -2.
