x =
, y = ![\frac{27}{4}](/tpl/images/1395/8344/3cbf0.png)
Step-by-step explanation:
Equate the first 2 parts of the ratios on both sides of the equation and solve for x.
Expressing the ratios in fractional form, then
6x = 15 ( divide both sides by 6 )
x =
= ![\frac{5}{2}](/tpl/images/1395/8344/21af6.png)
-----------------------------------------------------------------------------------
Equate the last 2 parts of the ratios on both sides and solve for y
2y =
× 3 =
( divide both sides by 2 )
y =![\frac{27}{4}](/tpl/images/1395/8344/3cbf0.png)
