Can someone help , im stuck on this one

Given :

Some points on two line j and k on the graph.

To Find :

The solution of the system.

Solution :

We know, solution of system is given by the points that satisfy all the equation given in the system.

From the given tables we can see that point ( 3, 18 ) satisfy both the equation j and k.

Therefore, the solution of the system is ( 3, 18 ).

i think this could be a possible answer (1 / 84) -1

good luck! : d

so, converting firstly the mixed fractions to improper fractions and then "adding".
