Help? Three students were given the expression shown to simplify. Use the drop-down menus to complete the statements about whether each student's answer is an equivalent expression. Then choose an expression that is equivalent. The first box’s options are: Correct / Incorrect The rest are in the other images

Tessa: -21x - 26

Bernette: -15x + 20

Lucy: 30 - 21x

Step-by-step explanation:

Put all like terms together

Tessa: 2 - 21x - 28

a) 2- 28 = - 26

Bernette: -5(3x-4)

1) You must multiply (-5) by 3x - 4

* -5(3x) = -15x

* -5(-4) = 20 (remember a negative X a negative = positive

Lucy: 2 - 21x + 28

Put all like terms together

a) 2 + 28 = 30
