3x - y = 17
x + y = - 5

x = 3 and y = -8

Step-by-step explanation:

eliminate your y value

4x = 12 (divide 12 by 4)

x = 3

plug x into whichever variable you want, I went with the 2nd one.

3 + y = -5 (subtract 3 from both sides to get y by itself)

y = -8

Check your answer by plugging both answers in

3 - 8 = -5

hey seth! : )

i’m not 100% sure, but i think it’s b

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
