i guess i got the answer ...
well..... four times a number b = 4×b = 4b
one more than is +1
and this = 17
now we need to put it all together and forma an equation .... so .. it will be
4b + 1 = 17
4b = 17 - 1
4b = 16
b = 16/4
∴ b = 4
4b + 1 = 17
4b = 17-1
4b = 16
b = 16/4
b = 4
so the answer is 4
hope it helps !!!!!!!!
