What is the answer to 2x-3=15 ? The answer to 2x-3=15 is x=9; Solve for x: 2x-3=15; The solution is x=9
We have 2x + 3 = 15. First, we move the non x terms to the RHS of the equation. To do this, we subtract 3 from both sides. Note: if a = b, then a - c = b - c. Therefore, 2x + 3 - 3 = 15 - 3. or, 2x = 12. Next, divide both sides by 2, which is the coefficent of x. Note: if a = b, then a ÷ c = b ÷ c. 2x / 2 = 12 / 2. x = 12 / 2
