Va rog sa ma ajutati si pe mine la mate !!! va rog

a) 3x-3 = x+7
3x - x = 7+3
2x = 10
x = 5
b) 2x+6-5 = x-7
2x-x = -7-1
x = -8
c) 4x+32 = 3x-6
x = -38
d) 1,4x-3,4x = 5/8 -4
-2x = (5-32)/8
-2x = -27/8
x = 27/16
e) 5x-3x+3 = 4-x
2x+x = 4-3
3x = 1
x = 1/3
f) 1/2 x - 3/8 + 5 = 7/2
1/2 x - 37/8 = 7/2 |*8
4x + 37 = 28
4x = -9
x = -9/4
g) 7/3 x - 7/2 = x + 13/6
14x - 21 = 6x + 13
14x - 6x = 13 + 21
8x = 34
x = 34/8 = 17/4
h) 25x - 6 = 25
25x = 25 + 6
25x = 31
x = 31/25
