Solve by substitution method. If the system does not have a single ordered pair as a solution, state whether the system is dependent or inconsistent.

6x+42y=30…………………(1)

X=5-7y……………………..(2)

**Solution:-**

Take 6 common from equation 1

6(x+7y)=30

X+7y=5……………………..(3)

Both lines are same .they have infinite number of solutions this type of system known as dependent.
