Question
Solve the following using the substitution method and find the value of x and y:
6x – 3y = -10
2x – y = -9
- -10, -9
- 6, 2
- -1, -3
- No solution
Hint:
Finding the solution by substituting the value of y in the other equation
The correct answer is: No solution
6x – 3y = -10
2x – y = -9
y = 2x + 9
6x – 3y = -10
6x – 3(2x+9) = -10
6x - 6x = 27 -10
0
no solution
