The value of d in the equation is d= 4m-w
<h3>How to calculate the value of d ? </h3>
The first step is to write out the equation given
m=1/4(w+d)
The value of d can be calculated as follows
m= w + d/4
Cross multiply both sides
4m= w + d
collect the like terms
4m -w= d
d= 4m-w
Hence the value of d in the equation is 4m-w
