Answer:
question 1) Add 7/4 to both sides. question 2) Divide 4 by both sides. question 3) x=15
Step-by-step explanation:
To solve for n in the equation d + 3n = 1, isolate n by subtracting d from both sides and then divide by 3.
To solve for n in the equation d + 3n = 1, we need to isolate the variable n. Start by subtracting d from both sides of the equation:
d + 3n - d = 1 - d
Simplify:
3n = 1 - d
Next, divide both sides of the equation by 3 to get the value of n:
n = (1 - d)/3
So, the solution for n is (1 - d)/3.
