Answer: y=7,x=3
Steps:
y = 2x + 1
3x + y = 16
Substitute y = 2x + 1
3x + 2x + 1 = 16
Simplify
5x+1=16
Isolate x for 5x + 1 = 16: x = 3
For y = 2x + 1
Substitute x = 3
y = 2 · 3 + 1
Simplify
y = 7
The solutions to the system of equations are:
y = 7, x = 3

The amount of sugar
in the starting solution contributes to a 36% concentration, so we have

units of sugar in the solution.
Into this solution, Sharon wants to pour
liters of water to obtain a smaller concentration of sugar in the overall solution:

So Sharon needs to add
liters of water to the solution to get the desired concentration.
