Question

What is the simplified expression for the expression below?7(x - 4) - 3(x + 5) A. 4x - 43 B. 4x + 1C. 4x - 13D. 4x - 9

Answer 1

4x - 43

Explanation:

This Question requires the concept of solving algebraic expressions.

Algebraic Expressions

Algebraic Expressions are expressions made up of alphabet variables and numbers and can be simplified using order of operations just like numerical expressions.

Example: 8(4x-6) = 32x - 48

Application

For this question, we will use the same concept as above to solve for the expression.

`7(x - 4) - 3(x + 5) = 7x - 28 - (3x + 15) \\ = 7x - 28 - 3x - 15 \\ = 4x - 43`
