Okay do first what you wanna do is combine common like terms in this case the common like terms are 2x and 4x and since 2x is a negative and 4x is a positive you would want to subtract which gets you 2x then you add 6 and 5 because they are both constants and they are both positive when you add it will get you 11 so it will be 2x +11
he expression 14 - 0.6t represents remaining fuel in the vehicle, where t represents number of days. ... A warning light comes on when the remaining fuel is 1.5 gallons or less.
