Question

3X - 2y = 2 5x - 5y = 10

Answer 1

Y= 3x over -2 x= 2+9

Answer 2

Answer:

x = -2 y = -4

Step-by-step explanation:

3x- 2y = 2 -> 15x - 10y = 10

5x - 5y = 10 -> 15x - 15y = 30

Substract one equation from another:

15x - 15x - 10y + 15y = 10 -30

5y = -20

y = -4

Plug in y into an equation

3x + 8 = 2

3x = - 6

x = - 2
