Question

Determine whether each equation has one solution, no solution, or infinite solutions show work. 3(x+5)+x=4x. 4(1-x)=5x+8. x+5+2x=5+3x

Answer 1

well first we need to solve this lets start with the first one :)
\[3(x+5)+x=4x\] how would you solve this? any ideas?

Answer 2

I solved the first one it 15=0 no solution

Answer 3

No soltuion is correct for that one what about #2?

Answer 4

I think it has one solution

Answer 5

yep thats correct =)

Answer 6

What about the 3rd one?

Answer 7

It is infinite solutions but what I need help with is how to show my work because I can't figure that out

Answer 8

ok so solving the equations =)
ok number 1 can you solve that?
Remeber we need to combine the like terms

Answer 9

But first there are parenthses so we must distribute

Answer 10

Number one was the only one I was able to show my work on it number 2,and 3 that I need help on

Answer 11

2)
1 Expand
4−4x=5x+8

2 Subtract 4 from both sides
−4x=5x+8−4

3 Simplify 5x+8−4 to 5x+4
−4x=5x+4

4 Subtract 5x from both sides
−4x−5x=4

5 Simplify −4x−5x to −9x
−9x=4

now u can get the answer just divide

Answer 12

So I divide -9 and 4

Answer 13

Is it -2.25

Answer 14

leave in fraction form :)

Answer 15

So it is -9\4 or 4\-9

Answer 16

-4/9 :)

Answer 17

for 3
1 Cancel 5 on both sides
x+2x=3x

2 Simplify x+2x to 3x
3x=3x

3 Since both sides equal, there are infinitely many solutions
Infinitely Many Solutions

Answer 18

For number two is 4\9 both negative numbers or just the 4

Answer 19

-4/9

Answer 20

OK so its just the four
