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
