Solve for n, o, p, q, r, s, t, u

$$u=4$$

Solution Steps

Consider the first equation. Expand \frac{0.5}{0.15} by multiplying both numerator and the denominator by 100.

$$\frac{50}{15}=\frac{n}{1.2}$$

Reduce the fraction \frac{50}{15} to lowest terms by extracting and canceling out 5.

$$\frac{10}{3}=\frac{n}{1.2}$$

Swap sides so that all variable terms are on the left hand side.

$$\frac{n}{1.2}=\frac{10}{3}$$

Multiply both sides by 1.2.

$$n=\frac{10}{3}\times 1.2$$

Multiply \frac{10}{3} and 1.2 to get 4.

$$n=4$$

Consider the second equation. Insert the known values of variables into the equation.

$$o=4$$

Consider the third equation. Insert the known values of variables into the equation.

$$p=4$$

Consider the fourth equation. Insert the known values of variables into the equation.

$$q=4$$

Consider the fifth equation. Insert the known values of variables into the equation.

$$r=4$$

Consider the equation (6). Insert the known values of variables into the equation.

$$s=4$$

Consider the equation (7). Insert the known values of variables into the equation.

$$t=4$$

Consider the equation (8). Insert the known values of variables into the equation.

$$u=4$$

The system is now solved.

$$n=4 o=4 p=4 q=4 r=4 s=4 t=4 u=4$$
