Please answer with all steps

Answer 1

Apply nodal analysis at v_1 v_1- V_2/5 + v_1 -v_3 /20 + v_1/10 = 0 4v_1 - 4v_2 + v_1 -v_3 + 2v_1 = 0 7v_1 -4v_2 -v_3 = 0 Apply nodal analysis at v_2 v_2 -v_1 /5 -10 + v_2 -v_3/10 = 0 2v_2 -2v_1 -100 + v_2-v_3 = 0 -2v_1 + 3v_2 -v_3 = 100 Apply nodal analysis at v_3 v_3 -v_1 /20 + v_3 -v_2/10 + v_3/5 = 0 v_3 -v_1 + 2v_3 -2v_2 + 4v_3 = 0 -v_1 -2v_2 + 7v_3 = 0 Solve 1 2 And 3 v_1 = 45.4545v v_2 = 72 .7272 V V v_3 = 27.2727V Apply nodal analysis at v_a Apply nodal analysis at v_a v_a-2/2 + v_a/3 + v_a - v/1 = 0 3v_a -6 + 2v_a + 6v_a-6v = 0 11v_a -6v = 6 Apply nodal analysis at v v_v_a/1 -2 + v/s = 0 5v -5v_a -10 + v = 0 -5v_a + 6v = 10 Solve 4 And 3 v_a = 2.667 v v = 3.8889v Resistor Valves And Source values are not given clearly Please make a content with clear values I will Send Answer from circuit
