Solve the equation when x=12 1/3 show your work 7x+8(x+1/4)=3(6x-9)-8

7(12  1/3) + 8(12 1/3 + 1/4) = 3(6(12 1/3) - 9) - 8

12 1/3 = 12.33
1/4 = 0.25

7(12.33) + 8(12.33 + 0.25) = 3(6(12.33) - 9) - 8
86.31 + 8(12.58) = 3(73.98 - 9) - 8
86.31 + 100.64 =  3(64.98) - 8
186.95 = 186.94 - 8
186.95 ≠ 178.94

False. The x, when 12 1/3 does not work inside this equation

hope this helps
