Gem and her three friends are going on a holiday. There is a buy 2 get one free offer on plane tickets.
Tickets cost £400 each.
If Gem and her friends are each expected to pay an equal amount towards their tickets, how much does each person pay?

£200

Step-by-step explanation:

4 friends - 4 tickets

2 tickets will cost £800

Divide the £800 between the 4 friends which is £200.

They will then get the other 2 tickets for free and have 4 altogether!

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x
