1d. 2w - 3=-9
w=-3
Right.
Thank you
You're welcome.
To solve the equation 12n = 36, we need to isolate the variable 'n' on one side of the equation.
Step 1: Divide both sides of the equation by 12:
12n / 12 = 36 / 12
n = 3
To check the solution, substitute the obtained value of 'n' back into the original equation:
12(3) = 36
36 = 36
The equation is correct, and the solution of n = 3 is verified.
To solve the equation n - 5 = 8, we need to isolate 'n' on one side of the equation.
Step 1: Add 5 to both sides of the equation:
n - 5 + 5 = 8 + 5
n = 13
To check the solution, substitute the obtained value of 'n' back into the original equation:
13 - 5 = 8
8 = 8
The equation is correct, and the solution of n = 13 is verified.
