Answer: x = 5

Step-by-step explanation:

We can set up an equation to solve for x:

3x + 4 = 19

We can subtract 4 from both sides:

3x = 15

We can divide both sides by 3:

x = 5

X=5

19-4=15
15/3=5

Or

5 x 3 = 15

Aleks [24]

Answer:

8 flowers in each bunch

Step-by-step explanation:

From this information, we can make the equation:

$23b-46=138$

Where $b$ is the number of flower in each bunch.

$23b-46=138$

<em>Add 46 to both sides</em>

$23b=184$

<em>Divide both sides by 23</em>

$b=8$

There are 8 flowers in each bunch.
