40 = -5 × [tex] \frac{n}{8} [/tex]
First, simplify 5 × [tex] \frac{n}{8} [/tex] to [tex] \frac{5n}{8} [/tex] / Your problem should look like: 40 = [tex] -\frac{5n}{8} [/tex]
Second, multiply both sides by 8. / Your problem should look like: 320 = -5n
Third, divide both sides by -5. / Your problem should look like: [tex] \frac{320}{-5} [/tex] = n
Fourth, simplify [tex] \frac{320}{-5} [/tex] to [tex]- \frac{320}{5} [/tex] / Your problem should look like: [tex] -\frac{320}{5} [/tex] = n
Fifth, simplify [tex] \frac{320}{5} [/tex] to 64. / Your problem should look like: -64 = n
Sixth, switch sides. / Your problem should look like: n = -64
Answer: n = -64
