Help pllsss ASAP!!!
have certain answers!! i try but i do not understand! help asap! give answers and walkthrough problems for me!
1. 2(x  3) = 2x (1 point)
one solution
no solutions
infinitely many solutions
2. 3(y  3) = 2y  9 + y (1 point)
one solution
no solutions
infinitely many solutions
3. 10x  2  6x = 3x  2 + x
one solution
no solutions
infinitely many solutions
4. 4(x +3) + 2x = x  8
one solution
no solutions
infinitely many solutions
Thank you!!

If you end up with
some x equals something, then there will be one solution
e.g. #4
4(x+3)+2x = x8
4x + 12 + 2x = x8
5x = 20 > some x equals something
x = 4 > one solution
if your x term drops out, and you end up with a true statement, there will be an infinite number of solutions
if your x drops out, but you end up with a False statement, there is no solution.
e.g. #2
3(y9) = 2y  9 + y
3y  27 = 3y  9
27 = 9 , what do you think, is it true or false ??
do the others the same way 
1.
2 ( x  3 ) = 2 x
2 * x  2 * 3 = 2 x
2 x  6 = 2 x subtract 2 x to both sides
2 x  6  2 x = 2 x  2 x
 6 = 0
False.
No solutions
2.
3 ( y  3 ) = 2 y  9 + y
3 * y  3 * 3 = 2 y  9 + y
3 y  9 = 3 y  9
True for all values of y.
infinitely many solutions
3.
10 x  2  6 x = 3 x  2 + x
10 x  6 x  2 = 3 x + x  2
4 x  2 = 4 x  2
True for all values of x.
infinitely many solutions
4.
4 ( x + 3 ) + 2 x = x  8
4 * x + 4 * 3 + 2 x = x  8
4 x + 12 + 2 x = x  8
6 x + 12 = x  8 Subtract x to both sides
6 x + 12  x = x  8  x
5 x + 12 =  8 Subtract 12 to both sides
5 x + 12  12 =  8  12
5 x =  20 Divide both sides by 5
5 x / 5 =  20 / 5
x =  4
one solution 
Thank you sooooo much guys!!! Got 100%!
