Answer:
You can't find y in this way
Step-by-step explanation:
You should know the value of x
But you can say
Y=7x
just multiply or add or divide to get your answer
20 = gh ( 4+1)
20 = gh (5)
20/5 = 5gh /5
20/5 = gh
Gh = 4
the connection is at 4 on x axis and 5 on y axis, so the solutions are x=4; y=5
