Answer:
5a + 6b + 7
step-by-step explanation:
16 + 8a -3a + 6a -9: subtract 9 from 16
7 + 8a -3a + 6b Now subtract -3a from 8a
5a + 6b + 7 is the final answer.
Answer:
x = - 7, y = 6
Step-by-step explanation:
7x + 7y = - 7 -----> equation 1
- 10x - 7y = 28 -----> equation 2
Add equations 1 & 2,
7x + 7y = - 7
- 10x - 7y = 28
___________
- 3x + 0 = 21
- 3x = 21
x = 21 / - 3
x = - 7
Substitute x = - 7 in equation 1,
7x + 7y = - 7
7y + 7x = - 7
7y + 7 ( - 7 ) = - 7
7y - 49 = - 7
7y = - 7 + 49
7y = 42
y = 42 / 7
y = 6
Answer:
95 over 2
because if it is 47 you double that since the denominator is 2 then you add the numerator and now you have your answer.
