2x + 10 + 3x = 7x + 12
wlad13 [49]

Answer:

<h2>x = -1</h2>

Step-by-step explanation:

2x+10+3x=7x+12\qquad\text{combine like terms}\\\\(2x+3x)+10=7x+12\\\\5x+10=7x+12\qquad\text{subtract 10 from both sides}\\\\5x+10-10=7x+12-10\\\\5x=7x+2\qquad\text{subtract}\ 7x\ \text{from both sides}\\\\5x-7x=7x-7x+2\\\\-2x=2\qquad\text{divide both sides by (-2)}\\\\\dfrac{-2x}{-2}=\dfrac{2}{-2}\\\\x=-1

Select steps that could be used to solve the equation 1 + 3x = -x + 4.
Olegator [25]

Answer:

A, C & D

Step-by-step explanation:

A) 1 + 3x = -x + 4  {subtract 1}

  1 + 3x -1 = -x + 4 - 1

       3x     = -x + 3         {add x}

     3x + x = -x + 3 + x

        4x    = 3       {Divide by 4}

       4x/x = 3/4

x = 3/4

C) 1 + 3x = -x +4            {Add x}

  1+ 3x + x = - x +4 + x      

   1 + 4x  = 4    {subtract 1}

        4x = 4 - 1

        4x = 3   {Divide by 4}

D) 1 + 3x = -x + 4        { Subtract 3x}

         1    = -x + 4 -3x

         1 = -4x + 4          Subtract 4}

      1 - 4 = -4x

        -3 = -4x              {Divide by -4}

       -3/-4 = x

x = 3/4  

          x = 3/4
