190=70+130(13/12)^{-t}

190 = 70 + 130 (\frac{13}{12})^{- t}

t = 1

Solution steps

190 = 70 + 130 (\frac{13}{12})^{- t}

Switch sides

70 + 130 (\frac{13}{12})^{- t} = 190

Move

70

to the right side

130 (\frac{13}{12})^{- t} = 120

Divide both sides by

130

(\frac{13}{12})^{- t} = \frac{12}{13}

Apply exponent rules

- t = - 1

Solve

- t = - 1 : t = 1

t = 1

2 7^{x - 1} = 3^{x + 5}

25000 = 50000 (0.9)^{x - 1}

5^{4 x + 2} = 7^{x + 5}

2^{2 x} + 2^{x + 2} = 32

243 = 3^{\frac{m}{10}}
