I think the answers would be B) 17
First we do brackets
(8900)-(1x89)
next we do the next bracket
8900-89
now we finish the equation
8811
Answer:
this may help you.look it once
<u>Given</u>:
The system of linear equations are
and 
We need to determine the solution to the system of equations using substitution method.
<u>Solution</u>:
The solution can be determined using the substitution method.
Let us substitute
in the equation 
Thus, we have;




Thus, the value of y is -17.
Substituting
in the equation
, we get;


Thus, the value of x is -13.
Hence, the solution to the system of equations is (-13,-17)
