Explanation:
3x-1=10x
Collecting like terms, that is numbers without letters to one side of the equation and numbers with laters to the other side
-1 = 10x - 3x
(-3x because as it crosses the equal to sign, = it becomes negative)
-1 = 7x
-1/7 = 7x/7 ( dividing both sides by 7 to make x be without a number)
-1/7=x
x = - 1/7
