The answer is 4.1
If the number is below 5, you round down, if it's 5 or above, you round up.
Use elimination
Multiply first equation by 4
12a - 8b = 56
12a + 9b = 39
Subtract both
-17b = 17
b = -1
Plug in -1 for b
3a - 2(-1) = 14
3a = 12, a = 4
Final answer: a = 4, b = -1
Answer:
x = 6

The slope should be
m= 2/3 (2 over 3)
20 in. Because if you divide it by three then multiply it by four you get your answer.
