Question

2/3 (x-1)+1/5(x+1)=1/2(x+4)-1

Answer 1

2/3 (X-1) + 1/5 (X+1) = 1/2 (X+4) - 1

1X/2 + 1×1/5 + 2X/3 - 2×1/3 = 1X/2 + 1×4/2 - 1

X/5 + 2X-2×1 / 3 + 1/5 = X/2 + 4/2 - 1

X+1 / 5 + 2X-2 / 3 = X+4 / 2 - 1

3X + 3 + 5×2X - 10 / 15 = X+4-2 / 2

(3X+3+5×2X-10)×2 = 15(X+4-2)

(10X + 3X - 7) × 2 = 15(X+2)

(13X - 7)×2 = 15X + 30

2×13X - 14 = 15X + 30

26X - 14 = 15X + 30

26X = 15X + 44

11X = 44

X = 4.
