what is the answer to x-4x+2x+6-7

Question

x-4x+2x=6-7

 

Answer 1

Bruce,  the equation x-4x+2x=6-7 simply combine like terms.  So:  -1x=-1;  Now divide both sides of the equation by -1 and x=1;  Check:  -4(1)+2(1)=6-7;  -4+3=6-7;  -1=-1

Answer 2

Hi Sidney,

 

Assume the equation (2nd version) is correct rather than the first expression.

 

We'll solve the equation step-by-step:

    1.  Given equation to solve:

             x - 4x + 2x = 6 - 7

    2.  Combine like terms on both sides:

             -x = -1

    3.  Multiply both sides by -1 for our answer:

             x = 1

 

We'll verify our answer by plugging it into the equation and see if both sides prove equal:

    x - 4x + 2x = 6 - 7

    1 - 4(1) + 2(1) = -1

    1 - 4 + 2 = -1

    -1 = -1

 

Since both sides of the equation have been proven equal with our answer plugged into the equation, we are confident that our answer is correct.

 

Thanks for submitting this problem and glad to help.

 

God bless, Jordan.
