Answer:
x = 1
Step-by-step explanation:
1. We first need to find the G.C.F of 25 and 15
i. by using tree factorisation or by writing down the multipels methord we find that the gcf of 25 and 15 is 5
15: 1, 3, 15, 5
25: 1,25, 5,
Hence we know that the gcf is 25...
now it says that 5 = 4x +1
hence we carry the one over to the 5 and the +1 changes to -1
so 4 = 4x
x = 1
