-((-7) +(4)(-12)+(-3)(11)+(-2))

90

Step-by-step explanation:

-((-7) + 4 × (-12) + (-3) × 11 + (-2))

-(-7 + 4 × (-12) + (-3) × 11 + (-2))

-(-7 - 48 - 33 - 2)

-(-90) → 90

Final Answer - 90

Hope this helped! :)

90

Step-by-step explanation:

Recall Order of Operations rules that require that computations inside parentheses must be done first.  Next, multiplication be done before addition or subtraction.  

-((-7) +(4)(-12)+(-3)(11)+(-2))  can be re-written as

-            ((-7) +(4)(-12)+(-3)(11)+(-2)), which in turn becomes:

-( -7 - 48 - 33 - 2 ), or

-( -55 - 35), or

- (-90), or 90

Step-by-step explanation:

3x - 2y = –9

3x−2y+2y=−9+2y

3x=2y−9/3x^3

=2y−9/3

x=2/3y−3

4x + 3y = 22

4x+3y+−3y=22+−3y

4x=−3y+22

4x4

=−3y+22/4

x=−3/4y+11/2
