A.
one solution

B.
infinite solutions

C.
no solution

Answer 1

Have you tried to solve it yet?

Answer 2

yes

Answer 3

Alright and can you show me the work?

Answer 4

no i did it in mah head sorry

Answer 5

i think its c

Answer 6

i just want to know if its correct

Answer 7

Thats not correct

Answer 8

ok

Answer 9

3(4x−3)−7x=5x−9
(3)(4x)+(3)(−3)+−7x=5x+−9(Distribute)
12x+−9+−7x=5x+−9
(12x+−7x)+(−9)=5x−9(Combine Like Terms)
5x+−9=5x−9
5x−9=5x−9
Subtract 5x from both sides.
5x−9−5x=5x−9−5x
−9=−9
Add 9 to both sides.
−9+9=−9+9
0=0 <----when the same number equals each other it means that there are infinite solutions.

Answer 10

ohhhhhhhhhhhhh ok

Answer 11

:)

Answer 12

can you elp with a couple others

Answer 13

Well i'm in school so ill help u with what i can until my free period is over :)

Answer 14

ok

Answer 15

Which expressions would complete this equation so that it has one solution?

4(2x – 3) – 4x =

Choose exactly two answers that are correct.

A.
4x – 12

B.
3x – 4

C.
3(2x – 6)

D.
4(x – 5)

Answer 16

I recommend trying each options out

Answer 17

4(2x−3)−4x=4x−12
(4)(2x)+(4)(−3)+−4x=4x+−12(Distribute)
8x+−12+−4x=4x+−12
(8x+−4x)+(−12)=4x−12(Combine Like Terms)
4x+−12=4x−12
4x−12=4x−12
Step 2: Subtract 4x from both sides.
4x−12−4x=4x−12−4x
−12=−12
Step 3: Add 12 to both sides.
−12+12=−12+12
0=0 <----is this one solution?

Answer 18

no

Answer 19

or
idk

Answer 20

4(2x−3)−4x=3x−4
(4)(2x)+(4)(−3)+−4x=3x+−4(Distribute)
8x+−12+−4x=3x+−4
(8x+−4x)+(−12)=3x−4(Combine Like Terms)
4x+−12=3x−4
4x−12=3x−4
Step 2: Subtract 3x from both sides.
4x−12−3x=3x−4−3x
x−12=−4
Step 3: Add 12 to both sides.
x−12+12=−4+12
x=8
Answer:
x=8 <----is that one solution?

Answer 21

oh no its infinite

Answer 22

thst is one the other is infinite

Answer 23

Yes what about the 2nd one?

Answer 24

its one answer right?

Answer 25

Yep

Answer 26

sooo imma say its b and c am i correct

Answer 27

ok
