Answer:

[tex]\boxed{x = 0}[/tex]

[tex]\boxed{y = 9/2}[/tex]

Step-by-step explanation:

[tex]\textbf{\textrm{1. Eliminate the 4 by making one equation negative}}[/tex]

-(3x + 4y = 18)

-3x - 4y = -18

-2x + 4y = 18

-5x = 0

x = 0

[tex]\textbf{\textrm{2. Plug X back into the equation to solve for y}}[/tex]

3(0) + 4y = 18

4y = 18

18/4 = y

y = 9/2
