Question

What is the answer for 3r=10+5 when r=10

Answer 1

Answer:

Step-by-step explanation:

What is the VALUE OF 3r=10+5 when r=10?

substitute 10 for r in 3r=10+5.  We get:

3(10) = 10 + 5, or 30 = 15.  This equation is FALSE when r = 10.

You could solve the equation for r, however:

3r=10+5 becomes 3r = 15, and so r = 5.  5 is a solution; 10 is not a solution.
