-\left(2a+bk-R\right)=4k-1
Multiply both sides of the equation by 4k-1.
-2a-bk+R=4k-1
To find the opposite of 2a+bk-R, find the opposite of each term.
-bk+R=4k-1+2a
Add 2a to both sides.
R=4k-1+2a+bk
Add bk to both sides.
-\left(2a+bk-R\right)=4k-1
Multiply both sides of the equation by 4k-1.
-2a-bk+R=4k-1
To find the opposite of 2a+bk-R, find the opposite of each term.
-2a+R=4k-1+bk
Add bk to both sides.
-2a=4k-1+bk-R
Subtract R from both sides.
-2a=bk-R+4k-1
The equation is in standard form.
\frac{-2a}{-2}=\frac{bk-R+4k-1}{-2}
Divide both sides by -2.
a=\frac{bk-R+4k-1}{-2}
Dividing by -2 undoes the multiplication by -2.
a=-\frac{bk}{2}+\frac{R}{2}-2k+\frac{1}{2}
Divide 4k-1+bk-R by -2.
