Question 917619
{{{x(m+3)+y(m-8)=z(m-2)}}}


{{{xm+3x+ym-8y=zm-2z}}} Distribute


{{{xm+3x+ym-8y-zm=-2z}}} Subtract zm from both sides.


{{{xm+ym-8y-zm=-2z-3x}}} Subtract 3x from both sides.


{{{xm+ym-zm=-2z-3x+8y}}} Add 8y to both sides.


{{{m(x+y-z)=-2z-3x+8y}}} Factor out the GCF m


{{{m=(-2z-3x+8y)/(x+y-z)}}} Divide both sides by X.
