Step-by-step explanation:

Here,

=

⇒4x-23° = 3x-5°

⇒4x-3x=(-5°)+23°

⇒x=18°

.°. x = 18°

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
