Question

Celia simplified the expression - 4x{1-3)-(2x+2). She checked her work by letting X-5 in both expressions. Her work for the
original expression is shown below.

Answer 1

Answer: I think it is the last one

Step-by-step explanation: if you work it out, it equally 6x-2

Answer 2

Answer:

6x-2

Step-by-step explanation:

$- 4x(1-3)-(2x+2)$

When x=5 the value of the expression is 28

Now we check with each expression given in the options

Plug in 5 for x in each option

$-6x-1=-6(5)-1=-30-1= -31$

$-6x+2=-6(5)+2=-30+2= -28$

$6x+1=6(5)+1=30+1= 31$

$6x-2=6(5)-2=30-2=28$

So 6x-2 gives us 28 when x=5
