3a + 6b = 45
2a - 2b = -12....multiply by 3
----------------
3a + 6b = 45
6a - 6b = - 36 ...(result of multiplying by 3)
---------------add
9a = 9
a = 1
3a + 6b = 45
3(1) + 6b = 45
3 + 6b = 45
6b = 45 - 3
6b = 42
b = 7
solution is : (1,7)
61 miles per hour, because if you divide 183/3 you will get 61.
Answer: y = 3+b
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
