Question

0.3x - 0.9x - 47 = 1

Answer 1

`\sf \: x = - 80`

Explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ 0.3x - 0.9x - 47 = 1

Then the value of x will be,

→ 0.3x - 0.9x - 47 = 1

→ -0.6x = 47 + 1

→ -0.6x = 48

→ x = 48 ÷ (-0.6)

→ x = 480 ÷ (-6)

→ [ x = -80 ]

Hence, the value of x is -80.

Answer 2

Given:-

• 
  `\tt \: 0.3x - 0.9x - 47 = 1`

`\:`

Solution:-

`\tt \: {0.3x - 0.9x - 47 = 1} \\ \\ \tt -0.6x - 47 = 1 \\ \\ \tt -0.6x = 1 + 47 \\ \\ \tt \: -0.6x = 48 \\ \\ \tt \: x = \cancel (48)/( - 0.6) \\ \\ \fbox{ \tt \: \red{x = -80 \: \: }}`

`\:`

The value of x is -80
