Answer 1

Answer:

Option (2) is correct

10b = 60

Step-by-step explanation:

 Given :  System of equations as

  5a+5b=25

 -5a+5b=35

We have find the resulting equation when elimination is used to solve the given system of equations.

Consider the given system of equations,

5a+5b=25  .....(1)

-5a+5b=35 ....(2)

Adding equation (1) and (2) , we get,

5a + 5b + (-5a + 5b) = 25 + 35

Simplify , we have,

5a + 5b -5a + 5b = 60

10b = 60

Thus, 10b = 60 is used to solve the given system of equations using elimination.

Answer 2

Adding we elimiate a's

5a+5b=25
-5a+5b=35 +
0a+10b=60

10b=60
