M+5n=p for m solve for indicated variable

M + 5n = p   Subtract 5n from both sides
M = p - 5n

Hi there!

Let's solve this problem step by step!
First we must realise that the money is being split into 7 parts. Plan G earns 2 parts and the arena the other 5 parts. This adds up to a total of 7 parts.

Plan G is paid £14,000 for the concert, and thus the 2 parts equal £14,000.

Finding the value of 1 part can quite easily be done by dividing the money by 2.
1 part of the money equals £14,000 / 2 = £7,000

Now the only thing that's left to do is multiplying the value of the 1 part by 5, in order to find the value of 5 parts (which is the total money that the age he earns).
5 parts equal £7,000 × 5 = £35,000

Hence, the answer is £35,000
