How to solve 3(n - 1) = 7n - 7

1. Factor the equation (x + 2)(x + 3) = 0. 2. Set each factor equal to zero: x + 2 = 0 and x + 3 = 0. 3. Solve for x: x = -2 and x = -3.

Question

$$3(n-1)=7n-7$$

Solve for n

$n=1$

Steps for Solving Linear Equation

Use the distributive property to multiply $3$ by $n-1$.

$$3n-3=7n-7$$

Subtract $7n$ from both sides.

$$3n-3-7n=-7$$

Combine $3n$ and $-7n$ to get $-4n$.

$$-4n-3=-7$$

Add $3$ to both sides.

$$-4n=-7+3$$

Add $-7$ and $3$ to get $-4$.

$$-4n=-4$$

Divide both sides by $-4$.

$$n=\frac{-4}{-4}$$

Divide $-4$ by $-4$ to get $1$.

$$n=1$$
