Check my work 3(x+1)-8=14-2(3x-4)
jeyben [28]

The value of x is 3

Step-by-step explanation:

<u>Equation:</u>

3(x+1)-8=14-2(3x-4)

<u>1. Open the brackets</u>

3(x+1)-8=14-2(3x-4)

3x + 3 - 8 = 14 - 6x + 8

<u>2. Bring all x variables on the left side</u>

3x + 6x = 14 + 8 + 8 - 3

<u>3. Solve</u>

9x = 27

x = \frac{27}{9}

x = 3

Therefore, the answer of x is 3.
