(42)/t =7

Solution

\frac{42}{t} = 7

t = 6

Solution steps

\frac{42}{t} = 7

Multiply both sides by

t

42 = 7 t

Switch sides

7 t = 42

Divide both sides by

7

t = 6

Find undefined (singularity) points:

t = 0

Combine undefined points with solutions:

t = 6

\frac{x + 1}{x - 1} = \frac{10}{5}

\frac{x ^{4} - 1}{x - 1} = 0

\frac{x - 2}{x - 2} = 1

\frac{3}{7 x - 1} = \frac{2}{3 x + 2}
