Y + 2.3 = 0.45x

-2y = 4.2x - 7.8

(2.4, - 1.2)

(-1, 2.5)

no solution

infinitely many solutions

Multiply the first equation by 2:-

2y + 4.6 = 0.90x

2y - 0.90x = - 4.6

second equation is

-2y - 4.2x = - 7.8

Adding:-

-5.1x = - 12.4

x = 2.4

-2y = - 7.8 + 4.2 (2.4) = 2.3

x = - 1.2

Answer x = 2.4 and y = - 1.2
