Question 268566
In this problem, each sentence is an equation. The sum of two numbers is 148 means you add the two numbers together.  Let x and y be the two unknown numbers.
So x+y=148
The larger number is 16 more than twice the smaller number
y=16+2x

SO your two equations are 
x+y=148
y=16+2x

You can plug the second equation into the first equation.
x+16+2x=148
3x+16=148
3x=148-16
3x=132
x=132/3
x=44
So now you know x=44. Just plug this into the first or second equation and you have your answer! Hope this helps!
