That says:
A is 5 less than E or

A = E take away 5

A = E - 5

That says:






If we add 1 to E we'll get 3 times A take away 4






or






E plus 1 equals 3 times A-4






E+1 = 3(A - 4)






So we have the system of equations:






E+1 = 3(A - 4)


A = E - 5






Can you solve that system by substitution?  If not


post again asking how.






Answer: E = 14, A = 9
