Answer:
(-3, 2)
Step-by-step explanation:
{3x=7y=5
{5x-2y=-19
solve....
maybe it was 3x + 7y = 5
and 5x - 2y = -19
2*(3x + 7y = 5)
7*(5x - 2y = -19)
-------------
6x + 14y = 10
35x -14y = -133
41x = -123
x = -3
y = ...
5*(-3) - 2y = -19
-15 - 2y = -19
2y = 4
y = 2
(-3, 2)
He is wrong. we are only looking at the last number which is 4
if we tripple 4 or 4*3 we get 12 which ends in 2, not 9
Answer:
1 + 1 - 0 = 1
When you add 1 + 1, you receive 2. Then when you subtract 1, you are left with 1.
Answer:
32 is composite and the rest are not. Hope this helps!
