X+y=3
x-y=-15
2x=-12
x=-6
y=-6+15=9

 Let, the numbers = x, y
So, x + y = 3
x - y = -15
x = -15 + y

Now, substitute the value of x in 1st equation, 
-15 + y + y = 3
2y = 3 + 15
y = 18/2
y = 9

Now, substitute the value of y in equation 2nd, 
x = -15 + 9
x = -6

In short, Your Numbers are 9 and -6

Hope this helps!

The equation to convert from degrees Celsius to degrees Fahrenheit is F=1.8C+32, whereas a simpler estimate for this conversion
anygoal [31]

Answer:

The answer to your question is  Equation 1  C = (F -32)/1.8

                                                      Equation 2   C = (F - 30)/2

Step-by-step explanation:

Data

Equation 1   F = 1.8C + 32

Equation 2  F = 2C + 30

Solve both equations for C

Equation 1

- Substract 32 in both sides

                  F - 32 = 1.8C + 32 - 32

- Simplify

                  F - 32 = 1.8C

- Divide both sides by 1.8

                  C = (F -32)/1.8

Equation 2

                   F = 2C + 30

- Substract 30 in both sides

                  F - 30 = 2C + 30 - 30

- Simplify

                  F - 30 = 2C

- Divide both sides by 2

                  C = (F - 30)/2

Solve the inequality −14a≥42, and write the solution in interval notation.
PSYCHO15rus [73]

The solutions to the inequality are (-∞, -3] or a ≤ -3 if the inequality −14a≥ 42 graph is shown in the picture.

<h3>What is inequality?</h3>

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have an inequality:

−14a ≥ 42

-a ≥ 3

a ≤ -3

a ∈ (-∞, -3]

Thus, the solutions to the inequality are (-∞, -3] or a ≤ -3 if the inequality −14a≥ 42 graph is shown in the picture.
