Solve the equation... 10x - 12 = 48 - 2x
hjlf
If you would like to solve the equation 10 * x - 12 = 48 - 2 * x, you can calculate this using the following steps:

10 * x - 12 = 48 - 2 * x
10 * x + 2 * x = 48 + 12
12 * x = 60   /12
x = 60 / 12
x = 5

The correct result is 5.

m_a_m_a [10]

Answer: y= 6x +14 and you would be able to feed 6 people cause when the graph starts the first 4 already counted for and since 6 is needed for each addition person that would mean 2 more people can be fed cause 26-14=12 and 12 divided by 6 is 2

You practice playing your guitar every day. You spend 15 minutes practicing chords and the rest of the time practicing a new son
Black_prince [1.1K]

Answer:

<h2>x=(y-105)/7</h2>

Step-by-step explanation:

Given that the total time taken to practice is given by the expression as

y=7(15+x)

Simplifying the expression we have

y=105+7x

Solving for x (that is making x subject of formula we have)

7x=y-105

Divide both sides by 7 we have

x=(y-105)/7

Therefore the expression is

x=(y-105)/7
