a+b=52
a/b=3 -------> a=3b
3b+b = 52 -------> 4b=52 --------> b=13
a = 52 - b
a = 52 - 13 = 39
a+b=52
a/b=3 -------> a=3b
3b+b = 52 -------> 4b=52 --------> b=13
a = 52 - b
a = 52 - 13 = 39

Hello Alyssa,
Let's use the following two equations to represent the problem.
x + y = 52
x/y = 3
Let's solve the second equation, okay?
x/y = 3
x = 3y <---------Multiplied both sides by y.
Now, substitute 3y for x in the first equation.
x + y = 52
3y + y = 52
4y = 52
y = 13 <---------This is the value for y.
x + y = 52
x + 13 = 52
x = 39 <--------This is the value for x.
Now, let's check our work. When we divide 39 by 3 do we get a quotient of 3? Yes. When we add the two values do they equal 52? Yes. The values check out and the solution is valid.
