Answer 1

HEY BUDDY HERE IS UR ANSWER ✌️✌️..

I TRIED MY BEST .... HOPE IT HELPS U...

ANSWER.:

• 3x / 7 - 4x/ 21 = 5
• (3x ×3 / 7 × 3 ) - 4x / 21 = 5
• 9x / 21 - 4x / 21 = 5
• 9x - 4x / 21 = 5
• - 5x = 5 × 21
• - 5x = 105
• x = 105/- 5
• x = - 21.

VERIFICATION:

• AS X= - 21
• then....
• (3× - 21 / 7 )- 4 × -21 / 21 = 5

using RHS ... and cancelling the bases of both ..

• 3 × (-3) - 4
• -9-4
• 5 ...
