DUE IN 10 MINUTES HEL AN DONT WASTE MY POINTS solve by substitution or elimination.

1) 5y=x

2x-3y=7

2) 7x+8y=25

9x+10y=35

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.
