Answer:
no solution (parallel lines)
Step-by-step explanation:
You observe that the coefficient in the second equation are all multiples of 3. Dividing that equation by -3 gives the two equations ...
The slopes are the same (2) and the intercepts are different (-11, 5), so the lines are parallel. There is no solution.
Answer:
1. 3
2. 33.3%
3. 33.3%
Step-by-step explanation:
Could be wrong, could be right.
Answer:
#1: x = 3; #2 c = 1/2; #3 = x = 22; #4 is correct (x = -8)
Step-by-step explanation:
for the first equation everything was right until 22x = 66
after
22x = 66
you must divide everything by 22
x = 3
that is for #1
for the second equation you copied down the question wrong
the negative is still there
6c - 8 - 2c = -6
combine 6c and -2c
4c - 8 = -6
the negative remains on the 8
add 8 to both sides
4c = 2
divide 4 to both sides
c = 2/4 or just 1/2
for the third equation you must first combine like terms
-3x + 25 + x + 21 = 2
combine -3x and x & 25 and 21
-3x + x = -2x
25 + 21 = 46
-2x + 46 = 2
then subtract 46 from both sides
-2x = -44
now divide both sides by -2
x = 22
that is your answer
number four should be correct
