Algebra, Trig Solve the System: 7x + Research Paper
Algebra, Trig Solve the system: 7x + 3y = -2, -7x -- 7y = (7x + 3y) + (-7x -- 7y) = (-2 + 14) 7x + 3y -- 7x -- 7y = 12 -4y = 12 y = -3 Substituting y for the first equation: 7x + 3(-3) = -2 7x -- 9 = -2 7x = 7 x = 1 x = 1, y = -3. Solve the syst Continue Reading...
