Answer:
x = -3
Step-by-step explanation:
2x-x=-5+2
x = -3
3x + 4y = 31
2x - 4y = -6
*The +4 and -4 in the center of the equation cancel out because 4-4 = 0*
3x = 31
2x = -6
------------
*add like terms*
3x + 2x = 5x
31 - 6 = 25
So now you should have this written on your paper ... > 5x = 25
*Divide by 5 on each side*
5x = 25

GCF(14; M) = 210
210|2
105|5
21|3
7|7
1|
210 = 14 × 3 × 5
The possible values of M:
14 × 1 = 14
14 × 2 = 28
14 × 4 = 56
14 × 7 = 98
14 × 8 = 112
14 × 11 = 154
14 × 13 = 182
