The steps are too quick and rushed until it is hard to see what is going on. The main mistake was when 2-8x, and 2 is carried over but the minus sign next to the 8x was not, but somehow it disappeared.

The charge of the number can be determined by looking at the operation at the left of the number. As the operation before 8 is a minus, It is minus 8 not 8

Should be -8x not 8x.

ReplyDeleteOn Line 3, the 8x should be -8x.

ReplyDelete-8x=45-9x

Deletehe should not change the -8x as it did not 'move' to the other side

ReplyDeleteThere is a mistake at Line 4. It should be -8x = 43-9x not 8x = 43 - 9x.

ReplyDeletefrom line 3 to 4 the minus sign for -8x disappears

ReplyDeleteThere is a mistake on line 4 . It should be -8 instead of 8 as he did not 'move ' the 8 so it should remain the same

On line 4, 8x should be negative 8x.

ReplyDeleteThe problem starts from line 4. It should be -8x = 43 - 9x . Therefore, line 5 should be x = 43 .
