Question

5-3x/4=8x what is value of x​

Answer 1

Given :   5 - 3x/4  = 8x

To Find : Value of x

Solution:

 5 - 3x/4  = 8x

Multiply both sides by 4

=> 20  - 3x  = 32x

=> 20 = 32x + 3x

=> 20 = 35x

=> 4  = 7x

=> x = 4/7

if ( 5 - 3x)/4  = 8x

=>  5 - 3x = 32x

=> 5 = 35x

=> x = 5/35

=> x = 1/7

Answer 2

Step-by-step explanation:

Given:

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

To find: Value of x

Solution:

Step 1: Take LCM in Left hand side

$\frac{20 - 3x}{4} = 8x$

Step 2: Cross multiply

$\frac{20 - 3x}{4} = \frac{8x}{1} \\ \\ 1 \times (20 - 3x) = 4 \times 8x \\ \\ 20 - 3x = 32x$

Step 3: Take 3x to RHS

$20 = 32x + 3x \\ \\ 20 = 35x$

Step 4: Swap sides

$35x = 20 \\ \\ x = \frac{20}{35}$

Step 5: Cancel common factors

$x = \frac{4}{7}$

Final answer:

$\bold{\red{x = \frac{4}{7}}}$

Hope it helps you.
