Question

Solve for x
3x+5=4x+9​

Answer 1

X= - 4

Explanation:

All like terms should be together (they go to the other side with opposite signs) so

: 3x-4x=9-5

3x-4x=4

- x= 4

. To remove the negative sign from the x multiply by - 1 on both sides.

-x(-1) = 4(-1)

X= - 4

Answer 2

x = -4

Explanation:

3x + 5 = 4x + 9

3x - 4x = 9 - 5

-x = 4

x = -4
