8x + 5 = 5x + 29
5 on the left passes to the right side as -5: 8x = 5x + 29 - 5
5x on the left passes as -5x to the left side: 8x - 5x = 29 - 5
Doing the operations: 3x = 24
the 3 on the left is multiplying the x, so it passes to the right side dividing: x = 24/3
Doing the operations: x = 8
Answer x = 8
