410^{-7}=710^{-9}(x-30)

Solution

4 \cdot 1 0^{- 7} = 7 \cdot 1 0^{- 9} (x - 30)

Solution

x = \frac{610}{7}

Decimal Notation

x = 87.14285 \dots

Solution steps

4 \cdot 1 0^{- 7} = 7 \cdot 1 0^{- 9} (x - 30)

Switch sides

7 \cdot 1 0^{- 9} (x - 30) = 4 \cdot 1 0^{- 7}

Simplify

4 \cdot 1 0^{- 7} : \frac{1}{2500000}

7 \cdot 1 0^{- 9} (x - 30) = \frac{1}{2500000}

Simplify

7 \cdot 1 0^{- 9} : \frac{7}{1000000000}

\frac{7}{1000000000} (x - 30) = \frac{1}{2500000}

Multiply both sides by

1000000000

7 (x - 30) = 400

Divide both sides by

7

x - 30 = \frac{400}{7}

Move

30

to the right side

x = \frac{610}{7}
