x=2/9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−4−3x=6x−6
−4+−3x=6x+−6
−3x−4=6x−6
Step 2: Subtract 6x from both sides.
−3x−4−6x=6x−6−6x
−9x−4=−6
Step 3: Add 4 to both sides.
−9x−4+4=−6+4
−9x=−2
Step 4: Divide both sides by -9.
−9x
−9
=
−2

The number of ways that the company can choose four workers is 40920 ways.
<h3>How to calculate the number?</h3>
From the information, the building company employs 3 laborers 12 joiners 8 electrician 4 plumbers. The total number of workers will be:
= 3 + 12 + 8 + 4
= 27 workers
It should be noted that combination will be used to choose the 4 workers. This is illustrated as
Combination formula
ⁿCr = n! / ((n – r)! r!)
n = the number of items.
r = how many items are taken at a time.
where n = 33
r = 4
ⁿCr = n! / ((n – r)! r!)
³³C₄ = 33! / (33 - 4)! 4!
= 33! / 29! 4!
= 33 × 32 × 31 × 30 / 4 × 3 × 2
= 40920 ways
