Answer:
♦ By substitution method :
⭐ x + 2y = -1
=> x = -1 - 2y -----------(1)
also, we have
2x - 3y = 12 -----------(2)
Putting value of x in equation (2) we get,
=> 2( -1 - 2y) - 3y = 12
=> -2 - 4y - 3y = 12
=> -7y = 12 + 2
=> -7y = 14
=> y = -2 -----------(3)
putting value of y in equation (1) we get,
=> x = -1 - 2y
=> x = -1 - 2 × -2
=> x = -1 +4
=> x = 3
Hence, x = 3 and y = -2
