Given the following system of equations: 2x + 3y = 12 2x - 2y = 2

What is the value of x + y? ​

5

Step-by-step explanation:

2x + 3y = 12

2x - 2y = 2 // subtract second equation from first

5y = 10

y = 2

x = (2 + 2y) / 2 = y + 1 = 3

x + y = 5

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
