Question

$3(3x+1)-(x-1)=6(x+10)$

Answer 1

3 (3x + 1) - (x - 1) = 6 (x + 10)

9x + 3 - x + 1 = 6x + 60

9x - x - 6x = 60 - 3 - 1

2x = 56

x = 28

Answer 2

3 (3x + 1)

3 × 3 × 3 = 9

9x + 3

6 (x + 10)

6x + 6 × 10 = 60

6x + 60

9x + 3 - x + 1 = 6x + 60

9x - 1x

(9 - 1)x = 8x

3 + 1 = 4

8x + 4 = 6x + 60

8x - 6x + 4 = 6x - 6x + 60

8x - 6x + 4 = 60

8x - 6x + 4 - 4 = 60 - 4

8x - 6x = 60 - 4

8x - 6x

(8 - 6)x = 2x

60 - 4 = 56

2x = 56

2x ÷ 2 = 56 ÷ 2

x = 56 ÷ 2

56 ÷ 2 = 28

x = 28
