Question

Maria's first step was to subtract 3x from bothsides of the equation : 5x-7=5x+4. Suppose she chose tosubtract 5x as her first step instead.What impact. If any, would this have on herprocess as she worked to solve the equation?Would it impact her final answer? Explain.

Answer 1

The equation :

5x-7=5x+4

If Maria should subtract 5x from both-side of the equation

The equation becomes

5x-5x -7 = 5x-5x +4

-7 =+4

whis is not true

-7 is not equatl to -4

Then there will be no solution to this equation
