so, does their value sum up to 30 or are there 30 coins in the mix?

also if there are 30 coins in the mix, are there equal amounts of php 20 and 10 coins or equal money worth of Php 10 and 20 coins?

the direction is use only one variable and write mathematical expression

it says expression so i can't use equal sign right?

my answer is like this

30=20+10

sorry i went afk

the variable would be x
it would become like 20x+10x as we donot know how much amount of money there is
