Well I have to find the equivalent resistor of these ones and I am having a hard time trying to find it so some help will be appreciated.

enter image description here

Figure 2. R1 and R8 combined. R4 and R9 combined.

    \$\begingroup\$ In general, homework questions enjoy/suffer a special treatment. We don't provide complete answers, we only provide hints or Socratic questions and only when you have demonstrated sufficient effort of your own, which you have not I am afraid. Otherwise, we would be doing you a disservice, and getting swamped by homework questions at the same time. Please revise your question showing your work and findings so far, in considerable detail.

  • \$\begingroup\$ There's an edit link below your question and you can show your progress using the built-in CircuitLab schematic editor. The button is on the editor toolbar. Double-click a component to edit its properties. 'R' = rotate, 'H' = horizontal flip. 'V' = vertical flip. Note that when you use the CircuitLab button on the editor toolbar and "Save and Insert" on the editor an editable schematic is saved in your post. That makes it easy for us to copy and edit in our answers. You don't need a CircuitLab account, no screengrabs, no image uploads, no background grid. \$\endgroup\$ – Transistor Oct 12 '19 at 12:31

    \$\begingroup\$ Re-read your text book section on series and parallel resistors, then do the math and you should then see wye the calculations work. \$\endgroup\$ – Nedd Oct 12 '19 at 13:18
  • \$\begingroup\$ I've put back your original image so that readers can make sense of your redrawn schematic. Now, as hinted by Nedd, see if delta-wye resistor networks helps you create a third step. Hit the edit link again ... \$\endgroup\$ – Transistor Oct 12 '19 at 13:37
