1)

x + 2y = 21

+ -x + 3y = 29

--------------------------

5y = 50

y = 10

x + 2(10) =21

x = 1

2)

6x + 6y = 30

+ 15x - 6y = 12

-------------------------------

21x = 42

x = 2

6(2) + 6y = 30

6y = 18

y = 3

aleksley [76]

Answer:

14

Step-by-step explanation:

Let's find (f-g)(x)

3x^{2} + 1 - (1-x)\\3x^{2} + 1 -1 + x\\3x^{2} + x

Now let's plug in x=2, so to find (f-g)(2)

3(2)^{2} + 2\\12 + 2 = 14
