Answer:
The larger van has 23 seats
Step-by-step explanation:
<u>Create a system of Equations:</u>
1. Define variables.
> let x=small van and y=larger van
2. create 2 equations based on the information given.
> y = 6 + x
> 2x + y = 57
3. Use any method to solve
Substitution: 2x + (6 + x) = 57. x=17
now plug x in to the original equation to solve for y (the larger van)
y = 6 + 17 and <u>y = 23</u>
Elimination: 2y = 12 + 2x
y = 57 - 2x
3y = 69 and <u>y = 23</u>
