Step-by-step explanation:
we will multiply the first ratio by unknown numbers and add 5 to each term. this is equal to 2:3 ratio. (ratios can be written as fractions as well)
now, we will use cross multiplication.
3(3n+5) = 2(5n-5)
now, we will further simplify.
9n + 15 = 10n - 10
9n - 10n = -10 - 15
-n = -25
n = 25
now, we will multiply n with each of the terms of the first ratio (3 and 5)
3n = 75
5n = 125
