Factor them and find the common grouping
3/14
3 is prime so no factoring of this fraction
19/63, 63 is prime so no factoring
if ya wanted the least common denomenator then
14 and 63
14=2*7
63=7*9
so the least common denomenator would be 2*7*9=126
3/14 and 19/63 turns into 27/126 and 38/126
Answer:
The answer to your question is:
x = 4
y = -1
z = -3
Step-by-step explanation:
3 x + 2 y + z = 7
5 x + 5 y + 4 z = 3
3 x + 2 y + 3 z = 1

Δz = -30
x = Δx /Δ = 40/10 = 4
y = Δy/Δ = -10/10 = -1
z = Δz/Δ = -30/10 = -3
To find the value take the b and divide it by two. then square it. here your b value is 2 so 2/2 is 1. squared is. 1.
