Question

7 ( x – 3 ) – 5 ( 3 – x ) = 11x – 5

Answer 1

\(7\left(x-3\right)-5\left(3-x\right)=11x-5.\)

\(\left(7x-21\right)-\left(15-5x\right)=11x-5\)

\(7x-21-15+5x=11x-5\)

\(12x-36=11x-5\)

\(12x-11x=36-5\)

\(x=31\)

Answer 2

7 (x - 3) - 5 (3 - x) = 11x - 5

7x - 7.3 - 5.3 - 5x = 11x - 5

7x - 5x - 21 -15 = 11x - 5

2x - (21 + 15) = 11x - 5

2x - 36 = 11x - 5

2x - 11x = 36 - 5

-9x = 31

x = 31:(-9)

x = \(\frac{-31}{9}\)

Answer 3

Mik làm sai rồi, như bn Ahwi mới đúng
