Solve for x: −3|2x 6| = −12 x = 1 and x = 5 x = −1 and x = −5 x = −9 and x = 3 no solution

1 answer:

5 0

-3|2x + 6| = -12
|2x + 6| = -12/-3 = 4
2x + 6 = 4 and 2x + 6 = -4
2x = 4 - 6 and 2x = -4 - 6
2x = -2 and 2x = -10
x = -2/2 and x = -10/2
x = -1 and x = -5

Please help one problem I’ll give brainliest..

Answer:

Your answer is infinitely many solutions

Step-by-step explanation:

To use elimination you have to get one of the variables to be the opposite of each other, so here you would do:

-2(2x+y = 7)

4x+2y= 14

You multiply the top by -2 to get the opposite of 2y, which is -2y. This in turn multiplies everything by -2 on the top solution giving us the top equation below.

-4x-2y = -14

+ 4x+2y = 14

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

0 = 0

If you add those 2 solutions then you get 0 = 0, which is infinitely many solutions
