Question

Find the value of x.

Answer 1

Given:-

• 
  `\rm \: (3x+9)°`

`\:`

• 
  `\rm(4x +3) \degree`

`\:`

Solution:-

• 
  `\rm \: (3x+9)=(4x+3)`

`\:`

• 
  `\rm \: 3x + 9 = 4x + 3`

`\:`

• 
  `\rm \: 3x - 4x = 3 - 9`

`\:`

• 
  `\rm \: -1x = -6.`

`\:`

• 
  `\rm \: x = \cancel ( - 6)/( - 1)`

`\:`

• 
  `\boxed{ \underline{\rm \purple{ \: \: x = 6 \: \: }}}`

`\:`

Therefore , the value of x is 6 !
