The mistake is on the second line of her work.

She wrote -2x + 4 when it should have been -2x -4 because she multiplied -2 by 2 the 4 would be negative: -2 x 2 = -4

Then adding 4 to the 7, x would be 11

Answer: She’s wrong because on the second line, she should’ve put -2x-4 instead of -2x+4 . X equals 11 because if you add 4 to 7 that’s what you’ll get ,
