Question

M=1/2 (d1+d2) solve for d1

Answer 1

Answer:  The required solution for $d_1$ is $d_1=2m-d_2.$

Step-by-step explanation:  We are given to solve the following equation for $d_1:$

$m=\dfrac{1}{2}(d_1+d_2)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

To solve the given equation for $d_1,$ we must take all the other terms on the right side of the equation.

From equation (i), we get

$m=\dfrac{1}{2}(d_1+d_2)\\\\\\\Rightarrow 2m=d_1+d_2\\\\\Rightarrow d_1=2m-d_2.$

Thus, the required solution for $d_1$ is $d_1=2m-d_2.$

Answer 2

D1= -d2+M is the answer because you would multiply d1 and d2 by 1/2, then add negative d2/2 to each side, then divide each side by 2/1.
