How do I solve for x

2 Answer

  • say your equation is y=mx+c
    to solve for x you rearrange the equation to make x the subject (x=...)
    to do this; you move the c to the other side;
    y-c=mx      becomes -c as its on the other side now
    then to get x on its own
    (y-c)/m=x     you divide by m as it is times by on the other side 

    then to solve, you will normally be given values for the other components (y, m, c) so you plug in the numbers and calculate x
  • Y=mx+c what the person said before
