Hi There!
The answer to your problem is A) 4
Move all terms containing x to the left, all other terms to the right
Add '-14' to each side of the equation.
[tex]14 + -14 + -1x = 10 + -14[/tex]
Combine like terms: 14 + -14 = 0
[tex]0 + -1x = 10 + -14[/tex]
[tex]-1x = 10 + -14[/tex]
Combine like terms: 10 + -14 = -4
[tex]-1x = -4[/tex]
Get your answer
[tex]x = 4[/tex]
Hope This Helps!
