Answer:
Step-by-stHere are some more examples of using substitution to solve simultaneous equations:
(1) 3x + y = 13. 5x -2y = 7. The coefficient of y in Equation 1 is 1. ...
(2) 2x + 4y = 10. 2x + y = 4. The coefficient of y in Equation 2 is 1. ...
(3) x - 5y = 7. 2x -4y = 8. ...
(4) 2x + 4y = 12. x + 8y = 30. ...
(5) 2x - 4y = 10. -4x+5y = -26. ...
(6) 6x + 2y = 10. 10x - 3y = 12.
