Question

Solve each equation.

Answer 1

$\\ \tt\hookrightarrow a/3=-5a$

$\\ \tt\hookrightarrow -a/3=5a$

$\\ \tt\hookrightarrow a=-a/15$

• So no solution except 0

#b

$\\ \tt\hookrightarrow 12-b=12.5b$

$\\ \tt\hookrightarrow 12.5b+b=12$

$\\ \tt\hookrightarrow (1+12.5)b=12$

$\\ \tt\hookrightarrow 13.5b=12$

$\\ \tt\hookrightarrow b=0.8888$

#c

$\\ \tt\hookrightarrow -0.1=-10c^2$

$\\ \tt\hookrightarrow c^2=0.01$

$\\ \tt\hookrightarrow c=0.1$
