2x + (x-1/3) = (5x+3/3)

2x +x -1/3 = 5x + 3/3

2x +x -5x -1/3 +1/3= 5x -5x + 3/3 +1/3

- 2x = 4/3

- 2x : 2 = 4/3 : 2

-x = 4/3 *1/2

-x = 2/3

x = - 2/3

d) 4/9

<h3>What is function?</h3>

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable)

Given:

f(x)= 2x+3 and g(x)= x²-5.

a) (f+ g)(3)

= f(3)+ g(3)

= 2(3)+3 + (3)²-5

=6+3+9-5

=13

b)  (f-g)(4)

= f(4)- g(4)

= 2(4)+3 - (4)²+5

=8+3-16+5

= 0

c) (fg)(-2)

= f(-2)*g(-2)

=[ 2(-2)+3][(-2)² -5 ]

=(-1)(-1)

= 1

d)  (g/f)(3)

= g(3)/f(3)

= 3²-5/ 2(3)+3

= 4/9
