Answer 2

ive gotton a b and c

Answer 3

1. 5x + 7 = 1/2(10x + 12)
5x + 7 = 5x + 6
false.....no solutions

2. 1/9(18x + 27) = 1 + x - 4 + 3x
2x + 3 = -3 + 4x
2x - 4x = -3 - 3
-2x = -6
x = 3
one solution

3. x + 3/4 = 3/4x + 3/4
x - 3/4x = 3/4 - 3/4
4/4x - 3/4x = 0
1/4x = 0
x = 0
one solution

4. 4 + 3x = 2x - 10
3x - 2x = -10 - 4
x = -14
one solution
