What is the solution: <br><br> 256x + 2 = 43x + 9
ruslelena [56]

<u>Answer:</u>

x = \bf \frac{7}{213}

<u>Step-by-step explanation:</u>

To find the solution to the equation, we have to rearrange the equation to make x the subject:

256x + 2 = 43x + 9

⇒ 256x + 2 - 2 = 43x + 9 - 2             [Subtracting 2 from both sides]

⇒ 256x = 43x + 7

⇒ 256x - 43x = 43x + 7 - 43x           [Subtracting 43x from each side]

⇒ 213x = 7

⇒ \frac{213}{213}x = \frac{7}{213}                                       [Diving both sides by 213]

⇒ x = \bf \frac{7}{213}
