Answer:

c

Step-by-step explanation:

Given the 2 equations

x + y = 3 → (1)

3x - y = 1 → (2)

Adding the 2 equations term by term will eliminate the term in y

4x = 4 ( divide both sides by 4)

x = 1

Substitute x = 1 into either of the 2 equations and evaluate for y

Substituting into (1)

1 + y = 3 ( subtract 1 from both sides )

y = 2

Solution is (1, 2 ) → c

Factor out the greatest common factor. 10a3b−6a2b2
podryga [215]

Answer:

2a^2b(5a-3b)

If not then the other way is

5a-3b

Step-by-step explanation:

The GCF of 10a^3b and -6a^2b^2 is 2a^2b

So divide by that you will get

2a^2b(5a-3b)
