Question like :x+1/2+x-2/3=9 class 7

Answer 1

Answer:

∴ x = 11

Step-by-step explanation:

solution,

or, x+1/2 + x-2/3 = 9

or, {(x+1) × 3/2×3} + { (x-2) ×2/3×2 = 9

or, 3x+ 3/6 + 2x-4/6 = 9

or, (3x+ 3) + (2x - 4) / 6 = 9

or, 3x + 3 + 2x - 4 = 9× 6

or, 3x + 2x + 3 -4 = 54

or, 5x - 1 = 54

or, 5x = 54 + 1

or, 5x = 55

or, x = 55/5

∴ x = 11
