Question

9 Which expression is equivalent to (2x − 5) −
(3x − 8)
A −x − 13
B −x + 3
C 2x − 16 D 5x − 3

Answer 1

I believe the answer is C or A

Answer 2

Answer is    -x+3

2x-5-(3x-8)   distribute the negative sign
= 2x-5+-1(3x-8)
= 2x + -5 + -1 (3x) + (-1) (-8)
= 2x + -5 + = -3x + 8  combine like terms
= (2x + -3x) + (-5 +8)
= -x + 3
