Question

You make 48 pints of pink paint by using 5 pints of red paint for every 3 pints of white paint.

Answer 1

I guessing you want us to find out how many pints of red and white paint is used 
ok let's start with this 
5x+3x=48 
simplify 
8x=48
divide 
x=6
now multiply to find how much paint 
5*6=30 
30 pint of red paint 
3*6=18
18 pints of white paint
