Someone pls help me.

you can check your solution for x by plugging it in the equation

Step-by-step explanation:

for example, if x = 4 and the equation is x + 5 = 9, plug in for x to get 4+5=9. That’s correct, so your solution for x is correct.

I hope this helped and please mark me as brainliest!

We check a solution to an equation by replacing the variable in the equation with the value of the solution. A solution should result in a true statement when simplified.

Step-by-step explanation:

Substitute the number for the variable in the equation.

Simplify the expressions on both sides of the equation.

Determine whether the resulting equation is true. If it is true, the number is a solution. If it is not true, the number is not a solution.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
