Is x=4 a solution to the equation 9x = 32 + x?
2 answers:
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:
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.
