Answer:

Step-by-step explanation:

1-(-7.2x+3.5)=5+3(7.4x-1) first parenthesis

1+7.2x-3.5=5+22.2x-3

7.2x-2.5=2+22.2x (x on one side and numbers on other)

22.2x-7.2x= -2-2.5

15x=4.5 divide by 15

x=-4.5/15

The given question is incomplete. The complete question is:

Omar rented a truck for one day. There was a base fee of $17.95, and there was an additional charge of 98 cents for each mile driven. Omar had to pay $23 when he returned the truck. For how many mile did he drive the truck?

Answer: Omar drove the truck for 5.15 miles

Step-by-step explanation:

Base fee = 17.95 $

Additional charge per mile = 98 cents = 0.98 $ ( 100cents = 1$)

Now Omar payed = 22 $

Let the miles he travelled = x

Now , $17.95+0.98\times x=23$

Solvimg for x :

$x=5.15miles$

Thus Omar drove the truck for 5.15 miles
