Answer/Step-by-step explanation:
✔️10x - 4y = -8
-5x + 6y = 10
Multiply the first equation by ½ to eliminate the x-term
Thus:
½ × 10x - 4y = -8 (eqn 1)
5x - 2y = -4
✔️-2x + 6y = 3 (eqn 1)
4x + 3y = 9
To eliminate the x-terms when adding to the second equation, multiply the first equation by 2
Thus:
2 × -2x + 6y = 3
-4x + 12y = 6
✔️3x - 8y = 1 (eqn 1)
6x + 5y = 12
To eliminate the x-terms when adding to the second equation, multiply the first equation by -2
Thus:
-2 × 3x - 8y = 1 (eqn 1)
-6x + 16y = -2
✔️-8x + 10y = 16 (eqn 1)
-4x - 5y = 13
To eliminate the x-terms when adding to the second equation, multiply the first equation by -½
Thus:
-½ × -8x + 10y = 16 (eqn 1)
4x - 5y = -8
