Answer:
2 and 8
Step-by-step explanation:
Larger number = y
Smaller number = x
---------------------------------
y = 2x+4
y - x = 6 -> y= x+6
---------------------------------------
x + 6 = 2x + 4
2 = x
y = x+ 6
y = 2 + 6
y = 8
Hope this makes sense!!!!
Answer:
x = -22
Step-by-step explanation:
6(x+15) = -42
x+15 = -7
x = -22
Answer is C. By solving x-y=-5 to x=-5+y and converting 2x + y = -1 into 2x + x + 5 = -1 the answer becomes -2 =x. By plugging that into 2 (-2) + y = -1, the answer is y=3. So your answer is C
