Determining the solutionfind the solution to the system of equations: x + 3y = 7and 2x + 4y = 81. isolate x in the first equation: 2. substitute the value for x into the second equation: 3. solve for y: x = 7 - 3y207 – 3y) + 4y = 814-6y + 4y = 814 – 2y = 8-2y = -6y = 3x + 3(3) = 74. substitute y into either original equation: 5. write the solution as an ordered pair: introdone0000000000
