Question

solution of equation 5x-1=8 is
​

Answer 1

Answer:

$5x - 1 = 8 \\ \\ 5x = 8 + 1 \\ \\ 5x = 9 \\ \\ x = \frac{9}{5}$

Answer 2

Given:

The equation: 5x - 1 = 8

What to find?

The value of x of the following equation.

Solution:

5x - 1 = 8

Take 1 to RHS,

⇒ 5x = 8 + 1

Add 8 and 1,

⇒ 5x = 9

Take 5 to RHS,

⇒ x = $\frac{9}{5}$

Divide 9 by 5,

⇒ x = 1.8

∴ Hence, x is equal to 1.8.

To verify:

5x - 1 = 8

Substitute the value,

⇒ 5(1.8) - 1 = 8

Multilpy 5 by 1.8,

⇒ 9 - 1 = 8

Subtract 1 from 9,

⇒ 8 = 8

∴ LHS = RHS

∴ Hence, verified.
