Answer:[tex]x+(3x+2)=30[/tex]

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

[tex]x+y=30[/tex] —-> equation A

Ginny’s car is 2 more than 3 times the length of Zach’s car

so

[tex]y=3x+2[/tex] —-> equation B

substitute equation B in equation A

[tex]x+(3x+2)=30[/tex]
