Question

Is x=4 a solution to the equation 9x = 32 + x?

Answer 1

Answer:

yes

Step-by-step explanation:

because 9*4=36 and well it's 36=32*? so 36-32 is 4

So well the solution is x=4

Answer 2

Answer:

Yes, it is.

Explanation:

For x = 4 to be a solution of the given eqⁿ, it must satisfy it. That is,

9x = 32 + x => 8x - 32 = 0

=> f(x) = 8x - 32

At x = 4,

f(4) = 8(4) - 32 = 32 - 32 = 0

Since, f(4) = 0, thus, x = 4 is a solution to the given eqⁿ.
