Solve the initial value problem for the linear differential equation : +6y = 7x, y(1) = 2. y = x+x-6 9. solve the differential equation r dy + xy + 2y - 2e-") dx = 0 subject to the initial condition y(1) = 0. (1-3-2)

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
