Solve the following system of equations algebraically<br> 3x-y=0<br> 5x+2y=22
Lyrx [107]

3x  -  y  = 0     ⇒   2(3x  -  y  = 0 )   ⇒   6x - 2y = 0

5x + 2y = 22  ⇒   1(5x + 2y = 22)   ⇒   <u>5x + 2y</u> = <u>22 </u>

                                                              11x         = 22

                                                                x          = 2

3x  -  y  = 0   ⇒   3(2) - y = 0   ⇒   6 - y = 0   ⇒   6 = y

Answer: x=2, y=6

3(x - 2) + 48 = -3x
kow [346]

Answer: X=-7

Step-by-step explanation:

Using PEMDAS;

Step 1: Distribute the "3" in the part of the equation "3(x-2)"

3x - 6

Step 2: Consider the equation as a whole with the newly part of the equation from step 1, as it is a part of the equation

Therefore, re-written as,

3x - 6 + 48 = -3x

Step 3: Evaluate the re-written equation

Using basic mathematics skills, we can evaluate the following,

3x - 6 + 48 = -3x ➡ -6 + 48 = -6x ➡ 42 = -6x ➡ -7 = x

As shown, the answer is x=-7.

Hello There!

The answer you have selected, (D) is correct!

To get the answer you simply add the two fractions together. and 9 + 4 = 13.

13/10 is also called an irrational fraction, the more you know~

Have a great day, and maybe brainliest?
