Question

solve: x/5 - 3 = x/4 - 8​

Answer 1

Answer:

= x/5 - x/4 = 3-8

= 4x/20 - 5x/20 = -5

= -x/20 = -5

= -x = -5 × 20 = -100

= x = 100

Answer 2

To find : the value of $x$

Given : $\frac{x}{5} - 3 = \frac{x}{4} - 8$

Solution :

• To find the value of $x$ we transfer terms with variables to LHS and terms with constants to RHS .  
• By performing simple addition and subtraction operations we find value of $x$.

          $\frac{x}{5} - \frac{x}{4} = -8 + 3 \\\frac{4x - 5x}{20} = -5 \\\frac{-x}{20} = -5 \\-x = (-5)\times 20 \\x = 100$

Hence , value of $x$ is $100$.
