So if an equation was f(x)=x+4
you would automatically change f(x) into y
so it would y-y=x(x-x)
so you plug in the x and 4 which is the first y and x
y-4=x(x-x)
you switch the numbers around
so your final answer would be x-4
For this, let's have:
n represent each number, the number after it is its place in sequence
/ means divide
n1 /2 = n2, etc.
14x45=630
43×2=86
(14×45)-(43×2)= 630-86=544
there would be 544 pens left
