Answer:
The expression:
[tex]7-3(4-2x)-10x\text{ }[/tex]is equivalent to:
[tex]4x-5[/tex]Explanation:
We want to write an expression equivalent to:
[tex]7-3(4-2x)-10x[/tex]First of all, we remove the bracket in the expression by multiplying the number outside the bracket by each of the elements inside the bracket.
[tex]\begin{gathered} 7-(3\times4)-(3\times-2x)-10x \\ =7-12-(-6x)-10x \\ =7-12+6x-10x \end{gathered}[/tex]Next, perform the addition and subtraction operations
[tex]-5+4x[/tex]This can also be written as:
[tex]4x-5[/tex]
