Answer:
![x+(3x+2)=30](https://tex.z-dn.net/?f=x%2B%283x%2B2%29%3D30)
Step-by-step explanation:
Let
x ----> the length of Zach's car
y ----> the length of Ginny's car
we know that
The sum of the lengths of both cars is 30 inches
so
----> equation A
Ginny's car is 2 more than 3 times the length of Zach's car
so
----> equation B
substitute equation B in equation A
![x+(3x+2)=30](https://tex.z-dn.net/?f=x%2B%283x%2B2%29%3D30)
