Question

(2 − 3)(1 − ) − (3 − )(3 + )

Answer 1

Answer:

your equation is wrong!! the answer is $10$

Step-by-step explanation:

the correct order of the equation is:

$(2-3)(-1)-(-3)(3)$

first, solve in the parentheses from left to right:

$(2-3)(-1)-(-3)(3)=\\(-1)(-1)-(-3)(3)=\\1-(-3)(3)=$

If we have 2 negative signs then we will change them to positive :

$1-(-3)(3)=\\1+3(3)$

now we have an equation with parentheses, we will multiply $3(3)$ because the parentheses go first.

$1+3(3)=\\1+9=10$
