Answer:
4x - 43
Step-by-step 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.
[tex]7(x - 4) - 3(x + 5) = 7x - 28 - (3x + 15) \\ = 7x - 28 - 3x - 15 \\ = 4x - 43[/tex]
