Question

For value of v, determine whether it is a solution to 21=5v+1. Is -7 a solution

Answer 1

Wym for "is -7 a solution"?
To plug for v? No, the value for v is 4.
21 = 5(4) + 1, check it. It's good! K?

Answer 2

Hello.

Given the equation:


`\mathsf{\boxed{5v + 1 = 21}}`

Testing for v = -7

-34 does not equal 21. Therefore, '-7' is not a solution.

Hope I helped.
