To check if the student is correct, we are going to solve the equation step by step.
Step 1 divide both sides of the equation by 5:
Step 2 take square root to both sides of the equation:
or
The equation has tow solutions, and .
I disagree with the student because is just one solution and not the only one; is also a valid solution of the equation.
Answer:
we can't see the words clearly
Step-by-step explanation:
The answer is 3.
the equation: 4x+6+3=17

4x=12
x=3
check by inserting 3 as x into the original equation
4*3+6+3=17
hope this helps!
