Answer:
x = [tex]2\dfrac{3}{7}[/tex]
Explanation:
[tex]\hookrightarrow 35.1 = 12.9 + 10.2x[/tex]
[tex]\hookrightarrow 10.2x = 35.1 - 12.9[/tex]
[tex]\hookrightarrow \dboxed{10.2x = 22.2}[/tex]
[tex]\hookrightarrow x =\dfrac{22.2}{10.2}[/tex] * 5
[tex]\hookrightarrow x = \dfrac{111}{51}[/tex]
[tex]\hookrightarrow x = \dfrac{37}{17}[/tex]
[tex]\hookrightarrow x = 2\dfrac{3}{7}[/tex]
