When Xiao Ming recalculates (2x + 3) (3x + 2) - 6x (x + 3) + 5x + 16, he gets x = 1, which is wrongly copied into x = - 1, but the value does not change

When Xiao Ming recalculates (2x + 3) (3x + 2) - 6x (x + 3) + 5x + 16, he gets x = 1, which is wrongly copied into x = - 1, but the value does not change

If we simplify, we can eliminate X. no matter x =?, the value of this formula is 22

Calculation: 5x + 2 (2x / 3 + 2) = 2 / 3 (X-6) + 2

5x+2(2x/3+2)=2/3(x-6)+2
5x+4/3x+4=2/3x-4+2
19/3x+4=2/3x-2
19/3x-2/3x=-2-4
17/3x=-6
x=-6÷17/3
x=-18/17
