Solve 0.3n-1=n+3?

$$0.3 n - 1 = n + 3 ?$$

Solve for n

$$n = -\frac{40}{7} = -5\frac{5}{7} \approx -5.714285714$$

Steps for Solving Linear Equation

Subtract n from both sides.

$$0.3n-1-n=3$$

Combine 0.3n and -n to get -0.7n.

$$-0.7n-1=3$$

Add 1 to both sides.

$$-0.7n=3+1$$

Add 3 and 1 to get 4.

$$-0.7n=4$$

Divide both sides by -0.7.

$$n=\frac{4}{-0.7}$$

Expand \frac{4}{-0.7} by multiplying both numerator and the denominator by 10.

$$n=\frac{40}{-7}$$

Fraction \frac{40}{-7} can be rewritten as -\frac{40}{7} by extracting the negative sign.

$$n=-\frac{40}{7}$$
