Answer:
Page 1:
A. exactly one solution
B. infinite many solutions
C. no solution
Page 2:
x = 3
Step-by-step explanation:
Page 1:
A. 3(x - 3) = 10x + 2
3x - 9 = 10x + 2
3x - 9 - 3x = -9
10x + 2 - 2 = 10x
-9 + 2 = -7
10x + 3x = 13x
-7 = 13x
13x / 13 = x
-7 / 13 = -7/13
B. -9x + 3 = -3(3x - 1)
-9x + 3 = -9x + 3
no matter what you'll end up with this
C. 2(3x - 1) = 6x - 1
6x - 2 = 6x - 1
there's no way to solve it :/
Page 2:
2/3x - 3 = 5
2/3x - 3 + 3 = 2/3x
5 - 3 = 2
2/3x = 2
2/3x / 2/3 = x
2 / 2/3 = 3
x = 3
