Answer: y=-3 x=7

Step-by-step explanation:

2y-3x=-27.............(1)

5y+3x=6.................(11)

Add (1) and (11)

2y+5y-3x+3x=-27+6

7y=-21

Divide both sides by 7

7y/7=-21/7

y=-3

Substitute y=-3 in 5y+3x=6

5(-3)+3x=6

-15+3x=6

3x=6+15

3x=21

Divide both sides by 3

3x/3=21/3

x=7

What is the greatest common factor of 8m, 36m3, and 12? 4 8 4m 8m

lidiya [134]

The greatest common factor is exactly as it sounds: the greatest factors of two or more expressions.

Factorize the numbers and identify all common factors. To get the GCF multiply all common factors:

$8m=2\cdot 2\cdot 2\cdot m,\\36m^3=2\cdot 2\cdot 3\cdot 3\cdot m\cdot m\cdot m,\\ 12=2\cdot 2\cdot 3$ .

Common factors are: 2 and 2, their product is 2·2=4, then the greatest common factor is 4.
