I'm a beginner.. Could you guys please help me..??
x = -19 a = 9
y = 11 b = -13

THANKS!!

First plug the variables' values into the corresponding spot. [(44*-19)(7*9)+(-13*11)] -28,221
now solve the parenthesis from left to right.
[(-836)(63)+(-143)]-28,221
now multiply from left to right
[(-52668)+(-143)]-28,221
add the to numbers in the parenthesis
(-52811) - 28221
now subtract
answer: -81032 hope that helps!

44x = 44(-19) = -836
7a = 7(9) = 63
by = (-13)(11) = -143
11x = 11(-19) = -209
(44x)(7a) = -52,668
(by)(11x) = 29,887
[(44x)(7a)+(by)(11x)] = -22,781
Therefore
[(44x)(7a)+(by)(11x)] - 28,221 = -51,002

Plug and chug baby, plug and chug!!!
Use BPEMDAS....Brackets, Parenthesises, Exponents, Multiply, divide, add, subtract and you will get the correct answer by plugging those babies in for the variables
[(836) (63)+ (143) (209)}-28221
-52668
-22781
-51002 is the answer
(tried in my head first)
