4x - 3y = 18 (1)

8x - 6y = 34 (2)

Divide equation b by 2

4x - 3y = 17

So now you have

4x - 3y = 18

4x - 3y = 17

--------------------subtract

0 - 0 = 1

0 ≠ 1

No solution

Answer is the last option

4x - 3y = 18

8x - 6y = 34

------------------------------

3x + 6y = 22 (1)

6x + 12y = 44 (2)

Divide equation 2 by 2

3x + 6y = 22 -------------same as equation 1

Subtract equation 2 from 1

0 = 0

Infinitely many solutions

Answer is the second option

3x + 6y = 22

6x + 12y = 44

What is the solution to the equation? 12 = |X| - 3 X= -36 or 36 X= -9 or 9 X = -4 or 4 X = -15 or 15​
quester [9]

Answer:

x = -15 or 15

Step-by-step explanation:

We can simplify |x| - 3 = 15 to |x| = 15 because we can add 3 on both sides due to -3 being outside of the absolute value bars. Next, we can say that x is either 15 or -15 because of the absolute value (|15| is equal to 15 and |-15| is also equal to 15).
