1. The information given in this problem, is:

- Wayne went on a 4 km hike.
- Wayne took a break at 4/3 km.
- Wayne took a drink of water at 10/3.

2. Then, when you convert the values from fractions to decimals, you have:

4/3 km=1.33 km
10/3 km=3.33 km

Solve 2x + 3y = 16 4x+10y = 40

Aleksandr-060686 [28]

Answer:

x = 5, y = 2

Step-by-step explanation:

First, find the value of x in respect to y:

2x + 3y = 16
2x = 16 - 3y

x = 8 - 3/2y

Then, substitute this expression into the second equation (Since we've established x is equal to 8 - 3/2y, we can put that in place of x):

4(8 - 3/2y) + 10y = 40

Then, distribute and solve for y:

32 - 6y + 10y = 40
32 + 4y = 40
4y = 8
y = 2

Now that we know what y equals, we can substitute the value of y in the equation to find x:
2x + 3(2) = 16
2x + 6 = 16
2x = 10

x = 5
