What is the value of n in the equation ?1/2 (n-4)-3=3-(2n+3)
N=0
N=2
N=4
N=6

n = 2

Step-by-step explanation:

1/2(n-4) - 3=3- (2n+3)

Expand the brackets.

1/2n-2-3=3-2n-3

Add or subtract the like terms.

1/2n-5=-2n

Add 2n and 5 on both sides.

1/2n+2n=5

Add like terms.

5/2n = 5

Multiply both sides by 2/5.

n = 5 × 2/5

n = 10/5

n = 2

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
