Question

What is the result of adding the system of equations?

2x + y = 4
3x - y = 6

x = 2
x = 10
5x = 10

Answer 1

Answer: 5x =10

Explanation:

Hi, to answer this question we have to solve the system of equations given. .By adding each equation we eliminate the variable Y .

a)2x + y = 4

+

b)3x - y = 6

________

5x =10

The result of adding the system of equations is the expression 5x =10.

if we continue and Isolate x :

x =10 / 5 = 2⇒ x=2

Feel free to ask for more if it´s necessary or if you did not understand something.

Answer 2

(2x +y) +(3x -y) = (4) +(6) . . . . . add the equations
x(2 +3) +y(1 -1) = 10 . . . . . . . . . collect terms
5x = 10 . . . . . . . . . . . . . . . . . . . simplify -- your last answer selection
