5x + 3 = 7x – 1. Find x
5x + 3 = 7x – 1
first we need to collect like terms
second is to undo addition and subtraction
third and the last is to undo multiplication and division
so again the first step is to put 5x and 7x in one side = 7x-5x
second put 3 and 1 in one side = 7x – 5x = 3 + 1
now we will solve the answer = 2x = 4
now we will divide by 2 to the both sides
2x/2 = 4/2
the answer now is x=2
