Answer:
1. -19x
3. 23 - 8x
5. -18x + 2y
Step-by-step explanation:
first: 3x - x = 2x
2x - 22x = -20x
-20x + x = -19x
second one:
8 - (-15) = 23
12x - 20x = -8 x
23 - 8x
third:
-10x - 8x = -18x
3y - y = 2y
-18x + 2y

Answer:
|3+x|=-3
Step-by-step explanation:
This equation has no solution because the answer would be - x=-3 X can't be negative 3 because if we inputed -3 into the absolute value, it wouldn't make any sense, as the absolute value of -3 is +3
Answer:
infinitely many solutions
Step-by-step explanation:
Given the 2 equations
2x + 2y = 18 → (1)
x + y = 9 → (2)
Equation (1) is twice (2)
Thus the equations are equal and will have infinite solutions
