Answer:
x=2
Step-by-step explanation:
6x+2x-9=7
Combine like terms on each side of the equation
8x-9=7
Add 9 to each side
8x=16
Divide by 8 on each side
x=2
 
                                
             
                    
              
              
                
                
Simplifying
6x + -2x + -9 = 7
Reorder the terms:
-9 + 6x + -2x = 7
Combine like terms: 6x + -2x = 4x
-9 + 4x = 7
Solving
-9 + 4x = 7
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '9' to each side of the equation.
-9 + 9 + 4x = 7 + 9
Combine like terms: -9 + 9 = 0
0 + 4x = 7 + 9
4x = 7 + 9
Combine like terms: 7 + 9 = 16
4x = 16
Divide each side by '4'.
x = 4
Simplifying
x = 4
