Start by solving one of the equations for one variable in terms of the other variable. It doesn't matter which equation or variabletry to pick an easy one: Nq  2Nd = 11 Nq = 11 + 2Nd Now substitute that value into the other equation and solve: 3Nq + Nd = 2 3(11 + 2Nd) + Nd = 2 33 + 6Nd + Nd = 2 7Nd = 35 Nd = 35/7 Now plug that into any of the previous equations to solve for the other variable: Nq = 11 + 2Nd Nq = 11 + 2(35/7) Nq = 11  10 Nq = 1
