Question

Simplifying algebraic expression

Answer 1

`\sf \: 5c - 9c + 3 = - 33`

Explanation:

Given information,

→ 5c - 9c + 3

→ where c = 9

Let's simplify the expression,

→ 5c - 9c + 3

→ 5(9) - 9(9) + 3

→ (5 × 9) - (9 × 9) + 3

→ 45 - 81 + 3

→ 45 - 78

→ -33 => final value

Hence, the final value is -33.

Answer 2

-33

Explanation:

Given algebraic expression:

`5c-9c+3`

To simplify the given algebraic expression using c = 9, substitute the given value of "c" into the expression and solve:

`\implies 5(9)-9(9)+3`

`\implies 45-81+3`

`\implies -36+3`

`\implies -33`
