Chapter SH, Problem 2.24EP

To determine

To calculate the value of $a$

Answer to Problem 2.24EP

  $a=\frac{cd}{2}+2b$

Explanation of Solution

Given information:

Given expression $\frac{2b-a}{c}=-\frac{1}{2}$

Formula used:

Cross multiplication method

Calculation: applying cross multiplication method in the given expression

  $4b-2a=-cd$

Subtracting 4b on the both sides

  $-2a=-cd-4b$

Multiplying by-1 on both sides

  $2a=cd+4b$

Dividing both sides by 2 and calculating the final answer

  $a=\frac{cd}{2}+2b$
