Question

6x - 3y = -9
-2x + y = 5
Solve the system of equation by substitution

Answer 1

Answer: No solution

Explanation:

-2 • (-3+y)/2 + y = 5

-2 = 0

Answer 2

Explanation:

6x - 3y = -9

divide by 3

2x- y= -3

2x=-3+y

x= (y-3)/2

substitute the value in 2nd equation

-2x +y =5

-2 × (y-3)/2 + y=5

-y+3+y =5

no solution.
