Answer: [tex]r=3[/tex]
Step 1
[tex](1/4)*(r-(5/2)) = 1/8 // - 1/8(1/4)*(r-(5/2))-(1/8) = 0(1/4)*(r-5/2)-1/8 = 01/4*(r-5/2)-1/8 = 0(1/4*8*(r-5/2))/8-1/8 = 01/4*8*(r-5/2)-1 = 0[/tex]
Step 2
[tex]2*r-6 = 0(2*r-6)/8 = 0(2*r-6)/8 = 0 // * 82*r-6 = 02*r-6 = 0 // + 62*r = 6 // : 2[/tex]
Divide
[tex]6/2=3[/tex]
