The equation that has an infinite number of solutions is 
<h3>How to determine the equation?</h3>
An equation that has an infinite number of solutions would be in the form
a = a
This means that both sides of the equation would be the same
Start by simplifying the options
3(x – 1) = x + 2(x + 1) + 1
3x - 3 = x + 3x + 2 + 1
3x - 3 = 4x + 3
Evaluate
x = 6 ----- one solution
x – 4(x + 1) = –3(x + 1) + 1
x - 4x - 4 = -3x - 3 + 1
-3x - 4 = -3x - 2
-4 = -2 ---- no solution
2x + 3 = 2x + 1 + 2
2x + 3 = 2x + 3
Subtract 2x
3 = 3 ---- infinite solution
Hence, the equation that has an infinite number of solutions is

<u>Complete question</u>
Which equation has infinite solutions?
3(x – 1) = x + 2(x + 1) + 1
x – 4(x + 1) = –3(x + 1) + 1
Answer:
As there is one math problem over there.
Lets see the question first:
It says that "A hair dryer is rated 
,if you use the dryer for 
.How much electric energy do you use ?"
Final answer = Electic energy 
Step-by-step explanation:
Electrical Energy 
.
The total amount of electrical energy used depends on the total power used by the electrical device and the total time they are used for.
So we have been given the power of the hair dryer 
Now the time it has been use for 
To calculate electric energy we will multiply both the terms.
Electric energy 
So electric energy used for the hairdryer is =
Answer:
18 girls
Step-by-step explanation:
2g = 3b
b = 12
g = girls
b = boys
2g = 3*12
2g = 36
g = 36/2
g = 18
The sum is 12x3+18x2-10x+8
Answer:
D
Step-by-step explanation:
3 and 1/4 = (3*4 + 1)/4 = 13/4. 3*(13/4) = 39/4 = 9 and 3/4 so it is D
Hope this helps!
