Question

x-8=y
2x-2y=16

subsitution method.

vijay · Answer

both equations are same, but they are in different format. cannot find the value.

anonymous · Answer

that is what i thought. but would that mean there isnt a solution or r there infinte soultions. bc i did no solutions and it was wrong

anonymous · Answer

If you are going to determine if there are infinitely many solutions or no solution... perform the substitution.

2x - 2(x - 8) = 16
2x - 2x + 16 = 16
16 = 16

Since 16 = 16 is a true statement, there are infinitely many solutions.  Even though the equations are the same, you should still perform the substitution.  Now, if the statement would have been false (i.e. 15 = 16), then it would have been no solution
