Question

If the first step in the solution of the equation -8 - 7x = -5x - 10 is "add 10," then what should the next step be?

2 Answer

  • -8 - 7x = -5x - 10....add 10 to both sides
    2 - 7x = -5x ......NEXT STEP.....add 7x to both sides
  • Answer:

    The next step should be ''add 7x''.

    Step-by-step explanation:

    Given : If the first step in the solution of the equation [tex]-8-7x=-5x-10[/tex] is "add 10,"

    To find : What should the next step be?

    Solution :

    Equation [tex]-8-7x=-5x-10[/tex]

    Step 1 - Add 10 both side,

    [tex]-8-7x+10=-5x-10+10[/tex]

    [tex]-7x+2=-5x[/tex]

    Step 2 - Add 7x both side,

    [tex]-7x+2+7x=-5x+7x[/tex]

    [tex]2=2x[/tex]

    Step 3 - Divide both side by 2,

    [tex]\frac{2}{2}=\frac{2x}{2}[/tex]

    [tex]1=x[/tex]

    Therefore, The next step should be ''add 7x''.
