Answer:
a. (-1/2, 5)
Step-by-step explanation:
The coefficients of x have opposite signs, so the x-terms can be eliminated by adding the two equations.
(2y -12x) +(3y +12x) = (16) +(9)
5y = 25 . . . . . . simplify
y = 5 . . . . . . . . .divide by 5
This matches only answer choice A.

<em>Check</em>
The other part of answer choice A is x = -1/2. We can test this to make sure it works:
2(5) -12(-1/2) = 16
10 + 6 = 16 . . . . . . true, the selected answer works OK
X= y(d-b) over a-c would be the answer
7. X=5
8. X=6
9. B=-3
10. G=3.4
X=B^1 + b^7 . i found my answer by you need to find the slope of the numbers between the table.
It is a high number and in the tens pop ace is 70
