Question

Help Please

Solve the following system of equations. Round your answers to the nearest tenth. Your answer will be in the form: (M,N). Find M + N, rounded to the nearest tenth.

5x+2y=7
-2x+6y=9

Answer 1

In the first equation, subtract 2y on both sides and you'll have 5x=7-2y. After that, divide both sides by 5, you get x=(7-2y)/5

In the second equation, substitute the value of x in the first equation to the x in the second equation, you get -2[(7-2y)/5]+6y=9

Do the necessary operations until you obtain the value of y. After that, you substitute the value of y in any of the equations
