How many solutions exist for the given equation?

Mathematics
1 answer:
grin007 [14]3 years ago
3 0

Answer:

One

Step-by-step explanation:

(x + 12) = 4x - 1

x + 12 = 4x - 1

12 = 3x - 1

13 = 3x

x = 13/3 = 4.3333333...

Since x only has one value, only one solution exists for the equation.

Using elimination, we add the equations, but this time from left to right. This process wants to elimination a variable. So 2x plus -2x equals 0. Moving on the next variable, 6y plus -y is 5y. On to the last variable, 18 plus 12 is 30. So we have this equation, 5y=30. 30/5 is 6, so y=6. We plug 6 into y in one of the equations you choose. In this case, I'm going to use the first equation. Plugging 6, we have this equation, 2x plus 36 is 18. 18-36 is -18. We then have this equation, 2x=-18. We know -9 times 2 is -18, so our x value is -9, So, our y=6, and our x=-9.

L is between M and N. If NL = 5x, LM = 3x, and NL = 15, find x.
Leona [35]

Answer:

x = 5

Step-by-step explanation:

Given that,

NL = 5x, LM = 3x, and NL = 15

L is between M and N.

To find,

The value of x.

Solution,

It is mentioned that, L is between M and N. So,

LM = LN

Put all the values,

3x = 15

⇒ x = 5

So, the value of x is equal to 5.
