\Delta xn=xn-\left(xn-x\right)
Use the distributive property to multiply x by n-1.
\Delta xn=xn-xn+x
To find the opposite of xn-x, find the opposite of each term.
\Delta xn=x
Combine xn and -xn to get 0.
x\Delta n=x
The equation is in standard form.
\frac{x\Delta n}{x\Delta }=\frac{x}{x\Delta }
Divide both sides by \Delta x.
n=\frac{x}{x\Delta }
Dividing by \Delta x undoes the multiplication by \Delta x.
n=\frac{1}{\Delta }
Divide x by \Delta x.
\Delta xn=xn-\left(xn-x\right)
Use the distributive property to multiply x by n-1.
\Delta xn=xn-xn+x
To find the opposite of xn-x, find the opposite of each term.
\Delta xn=x
Combine xn and -xn to get 0.
\Delta xn-x=0
Subtract x from both sides.
\left(\Delta n-1\right)x=0
Combine all terms containing x.
\left(n\Delta -1\right)x=0
The equation is in standard form.
x=0
Divide 0 by \Delta n-1.
\Delta xn=xn-\left(xn-x\right)
