Answer:
60
Step-by-step explanation:
The answer is 60
|2x + 12| = 18
First, break down the problem into 2 equations . / 2x + 12 = 18 and -(2x + 12) = 18
Second, solve the first equation. /

Subtract 12 from both sides. /

Subtract 18 - 16. /

Divide both sides by 2. /

Simplify. /
Third, solve the second equation. / -(2x + 12) = 18
Simplify your brackets. /

Add 12 to both sides. /

Add 18 + 12. /

Divide both sides by -2. /

Simplify. /

Simplify. /
Fourth, collect the solutions. /

Answer:
<h2><u><em>
60</em></u></h2>
Step-by-step explanation:
If 12 men are needed to run 4 machines. How many men are needed to run 20
we can solve with an equation
12 : 4 = x : 20
x = 12 * 20 : 4
x = 240 : 4
<u><em>x = 60</em></u>
<u><em>----------------------------</em></u>
check
12 : 4 = 60 : 20
3 = 3
<u><em>the answer is good</em></u>
