Solve using substitution:
3x + y = 14
2x - 6y = -24

x = 3

y = 5

Step-by-step explanation:

*tip = chose a variable and get by itself one side and then plug it into the other equation

3x + y = 14

y = -3x + 14

2x - 6(-3x + 14) = -24

2x + 18x - 84 = -24

20x = 60

x = 3

3(3) + y = 14

9 + y = 14

y = 5

step-by-step explanation:

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.
