Answer:
Yes, it is a solution
Step-by-step explanation:
9x+7y=-11
-2x-5y=30
substitute 5 for x and -8 for y and test:
9(5)+7(-8)=-11
45-56=-11 , this is true
-2(5)-5(-8)=30
-10+40=30 , this is true also
If your equation boils down to 12=12, then that means the variables you use don't even matter. Not only would this have infinitie solutions, but all solutions.
Work:
Solve for B
R=x (A+B)
distribute
R=Ax+Bx
-Ax both sides
R-Ax=Bx
÷x both sides
(R-Ax)/x=B
Answer: B=(R-Ax)x or B= (R/x)-A
Check your work:
Plug in B
R=x (A+(R-Ax)/x)
R=x (A+R/x-A)
R=x (R/x)
R=R
Answer is correct
