A is the answer (1/16,14)
We can see that 1/3 times 2=2/3
we can cancel the y terms
multily first equation by -2 and add to 2nd
-x-2/3y=-14
<u>1/4x+2/3y=6 +</u>
-3/4x+0y=-8
-3/4x=-8
times both sides by -4
3x=32
divide both sides by 3
x=32/3
sub back
1/2x+1/3y=7
1/2(32/3)+1/3y=7
16/3+1/3y=7
times 3 both sides
16+y=21
minus 16 both sides
y=5
(32/3,5)
(10 and 2/3,50
C is answer
an easier way would be to get rid of the fractions by multiplying the first equation by 6 and 2nd one by 12 but oh well

The answer to this question will be B
Answer:
10x-20
Step-by-step explanation:
(5×2x)-(5×4)
10x-20
2x -4y=20
-4y=-2x+20
Y= 1/2x - 5 that’s the answer
