agree with the first one,
the 2nd is wrong:
y-2x=5, x=y-3
use substitution
y - 2(y-3) = 5
y - 2y + 6 = 5
-y = -1
y = 1, then x = 1-3 = -2
one unique solution.
Classify each system. Give the number of solutions.
y=3(x-1)
-y+3x=3
My answer :
0=0
Infinitely many(consistent and dependent system)
y-2x=5
X=y-3
My answer:
0=2
No solution(inconsistent system)
Please
My answers are true or false, if my answers are false help me
