9 x + y i − 5 = − 12 + 4 ( 9 x − 5 ) + y i = − 13 ⟺ 9 x − 5 = − 13 an d y = 0 9 x = − 13 + 5 9 x = − 8 x = − 9 8 A n s w er : x = − 9 8 an d y = 0.
To solve the equation 9 x + y i − 5 = − 12 + 4 , we simplify it to 9 x + y i = − 3 . By separating the real and imaginary parts, we find that x = − 3 1 and y = 0 . Thus, the solutions are x = − 3 1 and y = 0.
