Answer:

a.
5 + (-3x) = -4

b.
5 + (-3x) = 4

c.
5 + (-3x) = 14

Explanation:

Given


5 + (-3x)

Required

Evaluate

(a) x = 3


5 + (-3x) = 5 + (-3*3)


5 + (-3x) = 5 + (-9)

Remove bracket


5 + (-3x) = 5 -9


5 + (-3x) = -4

(b) x = 1/3


5 + (-3x) = 5 + (-3*1/3)


5 + (-3x) = 5 + (-1)

Remove bracket


5 + (-3x) = 5 -1


5 + (-3x) = 4

(c) x = -3


5 + (-3x) = 5 + (-3*-3)


5 + (-3x) = 5 + (9)


5 + (-3x) = 14
