What is the answer for 7x - (7+3x)

4x - 7

Step-by-step explanation:

We can simplify this expression by subtracting the binomial (a bracket with two terms) and collecting like terms (numbers with the same variable).

When subtracting a binomial, are actually multiplying each term in the binomial by negative one.

7x - (7 + 3x)

= 7x - 1 (7 + 3x) Distribute - 1 to each of the numbers

= 7x + (7 * (-1) + 3x * (-1)) Multiply

= 7x + (-7 - 3x) Get rid of the brackets.

= 7x - 7 - 3x Combine like terms

= 4x - 7 Simplified expression
