Question

If a/b - d = 2c/b, find the value of c when a = 3, b = 4 and d = 5 ​

Answer 1

Answer: 23

Explanation:

first we put the values a=3,b=4 and d=-5. in a/b-d=2c/b equation which is given in the question. so,it gives us 3/4+5=2c/4,3+20=2c/4×4,3+20=c.so,the value of c is 23

Answer 2

`\huge\boxed{\sf c = -17/2}`

Explanation:

Given equation:

`\displaystyle (a)/(b) - d=(2c)/(b)`

Where, a = 3, b = 4, d = 5

`\displaystyle (3)/(4) - 5 =(2c)/(4) \\\\Take \ LCM\\\\(3-(5 * 4))/(4) = (c)/(2) \\\\(3-20)/(4) = (c)/(2) \\\\(-17)/(4) = (c)/(2) \\\\Cross \ Multiply\\\\-17 * 2 = 4 * c\\\\-34 = 4c\\\\Divide \ both \ sides\ by \ 4\\\\-34/4 = c\\\\c = -17/2\\\\\rule[225]{225}{2}`
