Question

How much is x/2-1=19​

Answer 1

x/2 - 1 = 19​

Explanation:

Step 1: Simplify both sides of the equation.

x/2 − 1 = 19

1/2x + −1 = 19

1/2x − 1 = 19

Step 2: Add 1 to both sides.

1/2x (+ 1)− 1 = 19 (+ 1)

1/2x = 20

Step 3: Multiply both sides by 2.

(2 ×) (1/2x) = 20 (× 2)

x=40

Answer 2

x=40
