x=12

Explanation:

"distribute brackets on both sides of the equation"

2x-6=x-1+7

2x-6=x+6

"subtract "x" from both sides"

2x-x-6=6

"add 6 to both sides"

x=6+6=12

color(blue)"As a check"

Substitute this value into the equation and if both sides are equal then it is the solution.

"left "=2(12-3)=2xx9=18

"right "=(12-1)+7=11+7=18

x=12" is the solution"
