Problema Solution
Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this.
7x + 7y = 7
x + 2y = 2
Answer provided by our tutors
Elimination method
7x + 7 y = 7 --> this can be simplified to x + y = 1
Two equations:
x+ y = 1
x + 2y = 2
Subtract the two equations
x + y = 1
-x -2y =-2
X will therefore be eliminated since x-x = 0
we will be left with
y-2y = -1
-y =-1
y =1
since x+y =1
x = y-1
x = 1-1
x=1
final answer
h
y=1
x=0
