Solve for x: (1/2)x - 3 = 7

Explanation:
Solving a linear equation means getting the variable by itself. Here, start by getting rid of the −3 on the left. Add 3 to both sides to keep the equation balanced: (1/2)x = 10. Now undo the multiplication by 1/2 by multiplying both sides by 2, which gives x = 20. The value x = 20 works because (1/2)*20 − 3 equals 10 − 3, which is 7.
