Answer:

[tex]\frac{15}{20} x-2=\frac{8}{20}[/tex]

Step-by-step explanation:

[tex]\frac{3}{4} x-2=\frac{2}{5}[/tex]

3/4 and 2/5 have a common denominator which is twenty so you can rewrite the equation with just knowing that

[tex]\frac{3}{4} =\frac{15}{20}[/tex]

[tex]\frac{2}{5} =\frac{8}{20}[/tex]

[tex]\frac{15}{20} x-2=\frac{8}{20}[/tex]

You can then multiply both sides by twenty to solve this equation.

Hope this helps.

15x = 48

Step-by-step explanation:

[tex]\begin{aligned}\rm\frac{3}{4}x-2&=\rm \frac{2}{5}\to(multiplied~by~20)\\\rm(20)\frac{3}{4}x-(20)2&=(20)\frac{2}{5}\\\rm 15x-40&=8\\\rm 15x&=8+40\\\rm 15x&=48\end{aligned}[/tex]
