The theater sells two types of tickets: adult tickets for $9 and child tickets for $4. Last night, the theater sold a total of 295 tickets for a total of $2170. How many adult tickets did the theater sell last night?

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

first one because it can't have a fraction in it
