X*2+1=10 then x=? Tell me the value of x

Trava [24]

Answer:

Step-by-step explanation:

$x \times 2 + 1 = 10$

$2x + 1 = 10$

Move constant to R.H.S and change its sign

$2x = 10 - 1$

Subtract the numbers

$2x = 9$

Divide both sides of the equation by 2

$\frac{2x}{2} = \frac{9}{2}$

Calculate

$x = 4.5$

Hope this helps..

Best regards!!
