Correct steps are shown

Correct simplified expression is:

[tex]-(7x - 3y) + 2(x+4) = -5x + 3y+8[/tex]

Solution:

Given that: Mara simplifies the expression

[tex]-(7x - 3y) + 2(x+4)[/tex]

Correct steps are:

From given,

[tex]-(7x - 3y) + 2(x+4)[/tex]

Use the distributive property,

a(b + c) = ab + bc

Therefore,

[tex]-(7x - 3y) + 2(x+4) = -7x +3y + 2x + 8[/tex]

Group the like terms

[tex]-(7x - 3y) + 2(x+4) = -7x + 2x + 3y + 8\\\\Combine\ the\ like\ terms\\\\-(7x - 3y) + 2(x+4) = -5x + 3y+8[/tex]

Thus the expression is simplified
