Please check Algebra

Please take a look at my work and let me know if I made any mistakes. You don't have to give me the answers. I'd just like to know if I made any mistakes so that I can correct them. Thanks!


1. 3x – 7 = 8
+ 7 +7
3x = 15
3 3 x=5

2. 14x -2 = 3x + 53

14x – 2 = 3x + 53
+2 +2
14x = 3x + 55
-3x -3x

11x = 55
11 11 x=5


3. 8x + 4 (6 + x) = 3 (x – 7) + 10x

8x + 24 + 4x = 3x – 21 + 10x
12x + 24 = -7x - 21
-24 -24

12x = -7x - 25
+7 +7

19x = -25 x = 44
-19 -19


4. 1.4x + 2.6 = 0.6x + 1.16
-1.16 -1.16
1.4x + 2.6 = 0.6x + 1.16
-1.4 -1.4

1.44 = -0.8x x = -1.8
0.8
