Question

Select all the equations that have the same solution as 2x-5=15

A.10
B.7.5
C.20
D.-5

Answer 1

To find the correct option that has the same solution as 2x - 5 = 15, we solve for x to get 10. Therefore, the matching equation from the options provided is A) 10, which is the same solution as x = 10.

Step-by-step explanation:

To determine which equations have the same solution as 2x - 5 = 15, we first need to solve for x. Adding 5 to both sides of the equation gives us 2x = 20. Then, dividing both sides by 2 results in x = 10, which is our solution. Now, we compare this solution to the options provided:

• A) 10
• B) 7.5
• C) 20
• D) -5

Since our solution for x is 10, the correct option that matches our solution is A) 10. The remaining options B, C, and D do not match the solution x = 10. Hence, the correct equation that has the same solution as 2x - 5 = 15 is A) 10.
