Answer:

[tex]x=\frac{82}{3}-\frac{7}{9}[/tex]  

Step-by-step explanation:

45x+35y=1230

[tex]\frac{45x}{45}=\frac{1230}{45} + \frac{-35y}{45} \\[/tex]

[tex]x = \frac{1230}{45} +\frac{-35y}{45}[/tex]

[tex]x = \frac{15(82)}{45} + \frac{-35y}{45}[/tex]

[tex]x=\frac{82}{3} +\frac{-7y}{9}[/tex]

[tex]x=\frac{82}{3}-\frac{7}{9}[/tex]
