Answer:
[tex]x=\frac{21}{4}[/tex]
Explanation:
[tex]\frac{2x+3}{15}\cdot \:10=\frac{9}{10}\cdot \:10[/tex]
[tex]2x+3-3=\frac{27}{2}-3[/tex]
[tex]\frac{2x}{2}=\frac{\frac{21}{2}}{2}[/tex]
[tex]x=\frac{21}{4}[/tex]
[tex]=5,25[/tex]
(Its the same as the answer above; though I wrote in fraction equation)
