Answer 1

hope it will help u.........

Answer 2

x = -7

Explanation:

4x-9 = 7x+12

Add 9 to both sides

4x = 7x + 21

Subtract 7x from both sides to further isolate the variable

-3x = 21

Divide both sides by -3

x = -7

Plug the value in to check your work:

4(-7) - 9 ? 7(-7) +12

-28 - 9 ? -49 + 12

-37 ? -37

-37 = -37
