before I respond I would like to see your attempts. By the way if you can solve for x, there is a solution. If it is impossible to solve, there is no solution. So tell me what x is in problems one (a tricky one) and two.
if you have 5 x and only 5 x on one side and 5 x and only 5 x on the other, then it is pretty hard to solve for x.
1. How many solutions does the equation have? 4x+3=2(2x+9)
a.one solution
b.no solution
c. infinite number of solutions
d. impossible to determine
2. How many solutions does the equation have? 4x+19=-9-6x
a.one solution
b.no solution
c. infinite number of solutions
d. impossible to determine
3. How many solutions does the equation have? -2(6x-4)=8-12x
a.one solution
b.no solution
c. infinite number of solutions
d. impossible to determine
4. Select all the equations that have only one solution.
a.4(2x+2)=8x+9
b.3x+(-4)=6x-4
c.9x-9=3(3x-3)
d.4x+5x+x=11x-3
5. select all the equations that have no solutions.
a.7x-12=8x+29-x
b.-4+5x=2(3x-4)
c.2(3x+5)=6x-19
d.-7+3+8x=2(6x-4)
I need answers!!! PLEASE HELP!!! Thank you in advance!:)

4 x + 3 = 2 ( 2 x + 9 )
5.
a.
7 x - 12 = 8 x + 29 - x
7 x - 12 = 7 x + 29
Incorrect
No solutions
b.
- 4 + 5 x = 2 ( 3 x - 4 )
- 4 + 5 x = 2 * 3 x - 2 * 4
- 4 + 5 x = 6 x - 8 Subtract 5 x to both sides
- 4 + 5 x - 5 x = 6 x - 8 - 5 x
- 4 = x - 8 Add 8 to both sides
- 4 + 8 = x - 8 + 8
4 = x
x = 4

c.
2 ( 3 x + 5 ) = 6 x - 19
2 * 3 x + 2 * 5 = 6 x - 19
6 x + 10 = 6 x - 19
Incorrect
No solutions
d.
- 7 + 3 + 8 x = 2 ( 6 x - 4 )
- 4 + 8 x = 2 * 6 x - 2 * 4
- 4 + 8 x = 12 x - 8 Add 8 to both sides
- 4 + 8 x + 8 = 12 x - 8 + 8
4 + 8 x = 12 x Subtract 8 x to both sides
4 + 8 x - 8 x = 12 x - 8 x
4 = 4 x
4 x = 4 Divide both sides by 4
x = 1
x = 18 / 4 = 2 * 9 / ( 2 * 2 ) = 9 / 2 = 4.5

- 7 + 3 + 8 x = 2 ( 6 x - 4 )
- 4 + 8 x = 2 * 6 x - 2 * 4
- 4 + 8 x = 12 x - 8 Add 8 to both sides
- 4 + 8 x + 8 = 12 x - 8 + 8
4 + 8 x = 12 x Subtract 8 x to both sides
4 + 8 x - 8 x = 12 x - 8 x
4 = 4 x
4 x = 4 Divide both sides by 4
