Solution for 8-2/5m=1/2(m-7) equation: 


m in (-oo:+oo)

8-((2/5)*m) = (1/2)*(m-7) // - (1/2)*(m-7)

8-((1/2)*(m-7))-((2/5)*m) = 0

(-1/2)*(m-7)+(-2/5)*m+8 = 0

(-2*m)/5-1/2*(m-7)+8 = 0

(-1/2*5*(m-7))/5+(-2*m)/5+(5*8)/5 = 0

5*8-1/2*5*(m-7)-2*m = 0

35/2-9/2*m+40 = 0

115/2-9/2*m = 0

(115/2-9/2*m)/5 = 0

(115/2-9/2*m)/5 = 0 // * 5

115/2-9/2*m = 0

115/2-9/2*m = 0 // - 115/2

-9/2*m = -115/2 // : -9/2

m = -115/2/(-9/2)

m = 115/9

m = 115/9
