Solve for n. 7n-4=31 n=

Isolate variable n: First, we need to isolate the variable n on one side of the equation. We can do this by adding 4 to both sides of the equation to cancel out the -4. 7n - 4 + 4 = 31 + 4Simplify both sides: Now, we simplify both sides of the equation by combining like terms. 7n = 35Solve for n: Next, we need to solve for n by dividing both sides of the equation by 7, the coefficient of n. 7n / 7 = 35 / 7Calculate value of n: Finally, we calculate the value of n. n = 5

Isolate variable n: First, we need to isolate the variable n on one side of the equation. We can do this by adding $4$ to both sides of the equation to cancel out the $-4$ . $7n - 4 + 4 = 31 + 4$
Simplify both sides: Now, we simplify both sides of the equation by combining like terms. $7n = 35$
Solve for n: Next, we need to solve for $n$ by dividing both sides of the equation by $7$ , the coefficient of $n$ . $\frac{7n}{7} = \frac{35}{7}$
Calculate value of n: Finally, we calculate the value of $n$ . $n = 5$
