Given:
{{{3x+4=x-5}}}


Combine similar terms. Remember to change sign when you move to the left or to the right: {{{3x-x=-5-4}}}
{{{2x=-9}}}


Isolate "x" by dividing 2 on both sides: {{{cross(2)x/cross(2)=-9/2}}}


{{{x=-9/2}}}, Answer


Chek by substituting to the equation:
{{{3(red(-9/2))+4=red(-9/2)-5}}}
{{{-27/2+4=-9/2-5}}}


Get Least Common Denominator to do the operations:
{{{(-27+8)/2=(-9-10)/2}}}
{{{-19/2=-19/2}}}, good
