Question

solve the equation $2x - 3 = 12$.
-12
30
4.5
7.5

Explanation:

Step1: Add 3 to both sides

To isolate the term with \( x \), we add 3 to both sides of the equation \( 2x - 3 = 12 \). This gives us \( 2x - 3 + 3 = 12 + 3 \), which simplifies to \( 2x = 15 \).

Step2: Divide by 2

Now, to solve for \( x \), we divide both sides of the equation \( 2x = 15 \) by 2. So, \( x=\frac{15}{2}=7.5 \).

Answer:

7.5
