4x+3y=8

8x+3y=14
=
-4x=-6
=
4x=6
1/4 x 4/7
do the top numbers first. 1 x 4 is 4do bottom numbers next 4 x 7 is 28
that leaves you with 4/28. But you have to reduce.
4/28 = 2/14 = 1/7 (notice I just cut both the top and bottom numbers in half each time I reduced until I couldn't reduce any more).
So, final answer is 1/7
Answer:
B
Step-by-step explanation:
Since the equation is all positive, the curve should concave towards the 4th quadrant.
27 :
complementary angle : 63
supplementary : 153
105 :
complementary : none cuz complementary angles add to 90
supplementary : 75
18 :
complementary - 72
supplementary - 162
complementary angles add up to 90 degrees and supplementary angles add up to 180
