Answer:

The least common denominator is 21.

Step-by-step explanation:

First, you must find the least common factor of the two:

3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30

7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70

Second, you must increase the fractions:

$\frac{1}{3}$ × $\frac{7}{7}$ = $\frac{7}{21}$ $\frac{3}{7}$ × $\frac{3}{3}$ = $\frac{9}{21}$

How do i use systems of equations to eliminate these two problems: -10x-8y=30 and -10x+5y=30

Papessa [141]

You would multiply negative on by -10x+5y=30 to get 10x-5y=-30
-10x-8y=30
10x-5y=-30

-13y=0
-13y/-13=0/-13
y=0
then you would plug y into -10x+5y =30
to get 10x=30
10x/10=30/10
x=3
the point would be (3,0)
