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

As a check

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

left =2(12−3)=2×9=18

right =(12−1)+7=11+7=18

x=12 is the solution
