Solve the system using substitution 5x-y equals 5 diveded by5x-3y equals 15?
5x - y = 55x - 3y = 15from the first equation:5x = 5 + y , substitute it in the second equation:5 + y - 3y = 155 -2y = 15-2y = 15 - 5-2y = 10y = -5Now,solve for x :5x = 5 +y5x = 5 -5 = zerox = zero
-3x plus 2y equals 9?
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
How do you solve this linear system using elimination method 4x-2y equals 6 and -7x plus 2y equals -15?
4x-2y = 6 -7x+2y = -15 Add both equations together in order to eliminate y: -3x = -9 Divide both sides by -3 in order to find the value of x: x = 3 Substitute the value of x into the original equations to find the value of y: Solution: x = 3 and y = 3
