Answer:
x=20
Step-by-step explanation:
10 separated into 5 groups is 10/5
5 goes into 10 2 times.
10/5=2
All you do is subtract the two numbers
-12x-10=0 since the X can't combine with non X numbers
The second table, because -1 x 3 = -3
-3 - 3 = -6 therefore, the second table matches the equation y= 3x -3
