5. this formula works out the tax you pay.
t = 0.3(e – 10 600)
t is the tax you pay in pounds.
e is the amount you earn in pounds.
alison pays £5200 tax.
work out the amount she earns.

first you take 5200 and divided by .3 = 17333.33 which is the total of the equation e minus 10600 so that means you have to take 17333.33 and add 10600 which =27933.33= E

thats not a system of equations, that is a solution
