# Answer to Question #3429 in Linear Algebra for Alicia

Question #3429

How do I solve this equation using the subtitution method:

<br>60+0.20(x-550)=120+0.15(x-800)

<br>60+0.20(x-550)=120+0.15(x-800)

Expert's answer

60+0.20(x-550)=120+0.15(x-800)

120 - 60 = 0.2x - 110 - 0.15x + 120

50 =0.05x

x = 1000

120 - 60 = 0.2x - 110 - 0.15x + 120

50 =0.05x

x = 1000
