<h2>Answer:</h2>

The value of x is:

                  x=45

<h2>Step-by-step explanation:</h2>

We are given a linear equation in terms of variable x and y as follows:

                    x-y=30----------(1)

Now, we are asked to find the value of x for the given value of y.

i.e. we have to evaluate the given equation for the given value of y.

Now we are given: y= 15

so by putting this value in equation (1) we have:

x-15=30

On adding 15 on both the sides of the equation we have:

x=30+15\\\\x=45

Answer:

n = -13

Step-by-step explanation:

√10 - 3n = 7 ⇔

⇔ 10 - 3n = 49 ⇔ We need to remove the square root. Ex: √n = 2 ⇔ n = 2²

⇔  -3n = 49 - 10 ⇔
⇔ -3n = 39 ⇔
⇔ n = \frac{39}{-3} = -13 (as -3 changes members, as it was multiplying, it now divides, conversion).

Find the real numbers x and y that make the equation true (x+6i)=(3-i)+(4-2yi)​
Ronch [10]

Answer:

x = 7

y = -7/2

Step-by-step explanation:

(x+6i)=(3-i)+(4-2yi)​

First look at the real parts

x = 3 +4

x = 7

Then look at the imaginary part

6i= -i -2yi

6 = -1-2y

Add 1 to each side

6+1 = -2y

7 = -2y

Divide by -2

7/-2 = y
