Question

Evaluate the expression x-7, if x=12

Answer 1

Substitute
`\(x\)` with
`\(12\)` in
`\(x - 7\)` .
`\(x - 7\)` when
`\(x = 12\)` becomes
`\(12 - 7 = 5\)`. Thus, when
`\(x = 12\)`, the value of the expression is
`\(5\)`.

To solve the expression
`\(x - 7\)` when
`\(x = 12\)`

Given expression:
`\(x - 7\)`

Given value:
`\(x = 12\)`

Substitute the value of
`\(x\)` into the expression:

`\(x - 7\)` when
`\(x = 12\)`

`\(12 - 7 = 5\)`

Therefore, when
`\(x = 12\)`, the value of the expression
`\(x - 7\)` is
`\(5\)`.
