Answer:
38.0
Step-by-step explanation:
first you divide then times
Answer:
Step-by-step explanation:
a. 3-4x=-7-4x
3=-7. no solution
b. 15 - 2x = -7x
15 = -5x
x=-3. one solution
c. 7y-21=6y-21
y=0
1. -3x+4=-3x+7
4=7
2. 10+2x = 5x+2
8=3x
x=3/8
3. x+5=x+5
Answer:
Group II is correct
Step-by-step explanation:
4x + 3 = x
4x - x = -3
3x = -3
x = -1
Here, the coordinates (-1, -3/5) represent (x,y)
Group II was correct because the value of x is -1
ii) Group I was wrong because the algebra given, only provided one unknown variable which was x.
