Please mark as brainlist

Step-by-step explanation:

3x + 5 - x - 2 5x - 7

__________ = _____

3 6

2x -3 5x - 7

____ = _____

3 6

6 ( 2x - 3 ) = 3 ( 5x - 7 )

12x - 18 = 15x - 21

21 -18 = 15x - 12x

3 = 3x

3/3 = x

1 = x

Answer 2

Given

• (3x+5/3) - (x-2)/3 = 5x-7/6

To find

• x

Solution

• 3x+5/3 - x-2/3 = 5x-7/6
• 3x+5-x-2/3 = 5x-7/6
• 2x+3/3 = 5x-7/6
• 6(2x+3) = 3(5x-7)
• 12x+18 = 15x-21
• 12x-15x = -21-18
• -3x = -39
• x = 39/3
• x = 13

∴ The value of x is 13

Verification

• 3x+5/3 - x-2/3 = 5x-7/6
• 3(13)+5/3 - 13-2/3 = 5(13)-7/6
• 39+5/3-13-2/3 = 65-7/6
• 44-15/3 = 58/6
• 29/3 = 29/3
• L.H.S = R.H.S
