Question

linear polynomials
simpiify :(4x-3)+(2x+6)-(-3x-4)​

Answer 1

Answer:

The currect answer is 9x+7

Answer 2

Step-by-step explanation:

$(4x - 3) + (2 + 6) - 1(3x - 4)$

$(4x - 3) + (2x + 6) - 3x + 4$

eliminate the redundant parentheses

$(4x - 3) + (2x + 6) - 3x + 4$

$4x - 3 + 2x + 6 - 3x + 4$

add the numbers

$4x - 3 + 2x - 6 - 3x + 4$

$4x + 7 + 2x - 3x$

combine like terms

$4x + 7 + 2x - 3x$

$3x + 7$

hence the final answer is

$3x + 7$
